I have been waiting to respond to this thread, hoping I would get a  
sunny day. The weather had been nice in the Seattle area until the  
last week in September, when it went completely to pot, with much  
lower temps and lots of rain. This is about a month earlier than such  
weather usually comes in, typically in late October, and it really  
seemed as if winter came a month early this year. We haven't had a  
really good day since then until today, although there have been  
brief sun breaks on and off. Today the clouds dissipated by early  
afternoon, and I made a beeline for the closest place to Seattle  
where I have found lots of odonates, about an hour from my house with  
the heavy Saturday afternoon traffic. I didn't really know what to  
expect, wondering if the long spate of adverse weather had wiped out  
dragonfly populations for the year.

Anyway, I didn't get to the lake until 15:00 hours, thanks to that  
traffic. The temperature was 63� F on the thermometer in my car,  
which is fairly accurate. These species were present and active:

Lestes congener - both sexes very common, but no pairs seen
L. disjunctus - few males
Aeshna canadensis - few males
A. palmata - males common, one ovipositing female
A. umbrosa - males common
Sympetrum vicinum - both sexes common, mating and ovipositing

These are all species normally present late in the season, several of  
them into November in some years. It appears that all of them  
survived the lengthy bad weather, and some may have been active  
during brief sunny spells. I doubt if any of them emerged since the  
weather turned bad around 24 September, so I think they were present  
as adults throughout that period. I caught quite a few of the  
darners, and none had especially worn wings, nor did the spreadwings  
and meadowhawks that I photographed, so I wonder if the fact that  
they were dormant for a considerable amount of time actually caused  
them to have less wing wear late in the season than I would have  
expected.

As it got later, a ridge to the west started obscuring the sun, and  
the sunlight left the lake by 16:00, as did all the odonates present.  
The Aeshna and Sympetrum disappeared, but the Lestes congener, which  
had been collecting in shrubs in the sun just to the east of the  
lake, began following the sun up into the trees. More and more of  
them flew up from the low shrubs and landed on leaves of large trees  
that were still in the sun. I was standing on a road right next to  
the lake, with the sky above me, so I could see this flight easily as  
one after another crossed the road. Some individuals flew sallies out  
from the leaves, presumably flycatching. The highest I saw one go was  
about 20 meters, which was about 2/3 of the way up to the treetops,  
but I wouldn't be surprised if they went higher. I had the feeling  
that a good proportion of the individuals present were moving up into  
the trees. By 16:20, the temperature had dropped to 57� F, and all of  
a sudden I could see no more movement among the Lestes. I assume they  
had gone to roost by then, and I can only assume that the roost sites  
of many individuals were well above the ground. Being that high, the  
sun would presumably hit them earlier in the morning than if they  
stayed down at the edge of the lake, and they were certainly able to  
remain active a bit longer by following the sun. Some individuals  
that I saw in the shrubbery had closed their wings, I should add, as  
they do when they go to roost.

This afternoon flight up into the trees is something that I haven't  
seen before, although I suspect it might be commonplace, and I just  
haven't been at the right place and time to see it. I suspect it has  
been written about for one species or another.

Add rubbing/striking vegetation (especially common in females) and the 
tendency of the wings to become more brittle with age so minor injuries 
sustained earlier in life cause bits to break off in response to flight 
stresses.  Perhaps attacks by small birds (larger birds tend to 
overpower the dragonfly very quickly if they do grasp it by more than a 
wing tip),

I've seen dragonflies with tattered wings many times - great chunks missing
from the trailing edges- Whats causes this?
Is it the result of clashing with other dragonflies? parasites? or just normal
wear and tear for a busy dragonfly?

remember dragonflies, like many of the hemimetabolous insects, have a 
distributed nervous system with high levels of 'delegation'.  So thorax 
activities are controlled by the three thoracic ganglia and the abdomen 
by the abdominal ganglia; and with no instructions from up front these 
will continue to go about maintenance activity and local comfort 
movements until the metabolism runs down.  Headless larvae 'leak', but 
the thin neck of adults often seals,

I have anecdotical evidence of a male Sympetrum striolatum which I had 
forgotten in its envelope, that was still moving his legs 14 days after 
netting. In my experience, specimens of Sympetrum and Lestes (including 
Chalcolestes) resisted starvation for quite many days.
On a physiological perspective, I would say that the number of days a dragon 
/ damsel survives without food be related to several factors, including the 
severity of injuries caused by capture, which could not be obvious, and the 
temperature they experience during starvation: at high temperatures they 
should die earlier because of their higher metabolic rate, and vice versa. 
On an ecological perspective, I think that species that fly in autumn (like 
some Sympetrum and Lestes in Italy) might be adapted to survive without 
feeding for longer periods compared to those that fly in spring or summer, 
since they are more likely to cope with periods of bad weather.

I have seen Cordulegaster erronea (Tiger Spiketail) flying in light rain
also. Since they live in heavily shaded under story conditions, the
light rain and the darkness that accompanies it is not much different
from the low-light conditions they typically fly in. As long as it is
warm enough, and not a downpour, it probably does not make much
difference. Most pond species disappear into the vegetation as soon as
it gets cloudy. 

 

A couple of us here in central Ohio have noted that for river species,
heavy rain is typically accompanied by quickly raising water levels. We
have hypothesized that not only might the heavy rain physically knock
adults down, making them easy prey, but the rising water levels may wash
away larvae that have moved to the stream edge and are about to emerge,
causing a one week or longer drop in population levels. Larvae that are
on the bottom and away from the stream edge are protected by rapidly
reduced current speed near the bottom - but those that are about to
crawl up, or are crawling up, are not so protected. Sorry - no data to
support this - just anecdotal observations.

Hi!

 

We had a discussion about that back here in Finland after members of the
Finnish Dragonfly Society observed a drop in the numbers after rainy
periods and the general consensus was that if most of the specimens
don't get to feed for an extended period of time due to weather
conditions, the numbers will drop as the dragons simply die off. Does
someone on the list have actual research data on the survival of dragons
when deprived of food? 

 

I do recall seeing Aeshna grandis fly in light rain but most species
seem to avoid hunting in rainy conditions.

 

This year demonstrated the effect here pretty well - the early season
was fantastic and a massive number of the early records were broken.
However in "early mid-season" the weather worsened dramatically for a
period of time, which caused a significant drop in the number of dragons
observed. Some fairly common species suddenly weren't that common at
all.

It may partly depend on what sort of rain.  Here in upstate NY when there is
a sharp cold front and rain is accompanied by wind and temperature lowering,
the dragonflies essentially disappear, to be replaced (during the summer
that is) by scads of tenerals a few days later.  I interpret this as
destruction of adults by the storm (not necessarily the rain).  Whether they
are killed directly or rendered more easily caught by birds I have no idea.
In many years such storms do not occur, and early season odes can persist
until very late (Ophiogomphus rupinsulensis in late September; Tachopteryx
in late August.)

Hi,

Here in my corner of South Carolina, it's rained almost five inches  
in the last week, with hard rains on about four days in a row.  It  
turned sunny again yesterday.

How does rainfall like that affect dragonfly numbers?  Does that  
usually knock them down for a while?  I'm asking because I have some  
students doing a research project on a common species, which is  
suddenly less common!  I'd like to be able to guess whether the  
dropoff is weather related and the odes will bounce back, or if it's  
more likely seasonal and they won't be coming back.

CH

Hi
I'm trying to learn more about dragonfly combat, and would be grateful if
someone could point me towards a suitable authority or document(s).I'm looking
for information on actual physical combat between dragonflies rather than the
threatening displays or flying skill demonstrations that can occur between
conspecific dragonflies.

Thanks

Ben Evenden

On September 24 a juvenile band-winged dragonlet was found at a newly 
created wetland in eastern Lake County, Ohio (just east of Cleveland).  The 
following day seven juveniles were found and on the next day approximately 
20 juveniles were found.  This past week, only a single juvenile female was 
seen on Wednesday and Thursday and none were found on Friday.

The question is what happened to the dragonlets.  Did they disperse to parts 
unknown or have they just dispersed locally to return later when ready to 
breed?  Does anyone have any idea about their life history?

Here are a few brief notes about the wetland where they were found.  The 
wetland was constructed during June of this year and due to the drought did 
not begin to fill until mid-July.  There are three separate wetlands in the 
complex and the dragonlets were found in only one of the wetlands.  The 
wetland in which they were found was the first that was completed.  The 
other two wetlands were completed in late June early July.  There are 
hundreds of wandering gliders breeding in the wetland where the dragonlets 
were found as well as familiar bluets.  From the time that the wetland began 
filling to when the first gliders began hatching was 6 weeks. the time till 
the dragonlets were found was about 7-8 weeks.  Familiar bluets began 
hatching after 7-8 weeks also. There have only been a few wandering gliders 
hatching out of the other two wetland thus far, no bluets or dragonlets.

If you are a member of DSA or had registered with OdonataCentral earlier, you 
will have already received this email and I apologize for the duplication. For 
everyone else: 


At long last the new OdonataCentral is now up and running.  It can be
reached by any of the following url's :  www.odonatacentral.org,
www.odonatacentral.net, www.odonatacentral.com

Please note that if you linked to the old site using
http://odonatacentral.bfl.utexas.edu you should be redirected to the new site, 
but only to the home page. 


The site has been completely overhauled and now uses php with Oracle as its
database backbone.  This provides for a much more efficient navigation and
delivery of information.

Some of the major improvements and additions to look for include, but are
not limited too:

(1)   a visual redesign

(2)   MyOC.  This feature allows users to login and use customized
interfaces.  Much like MyAmazon or MyEbay, the site remembers you and keeps
track of favorite locations and will allow you to easily track your record
submissions, or if you are a Record Administrator, manage the records in
your area.  We plan to implement much more with this, including a set of
preferences that will allow you to choose scientific, common or both names
to be used throughout the site.

(3)   The site is now worldwide.  The interfaces built will allow for the
addition of records from anywhere.  Features such as checklists, field
guides and the map distribution viewer are no longer limited in scope (just
in the underlying records!).

(4)   MyRecords interface is now much improved in terms of tracking and
submitting.  Submitted Records are automatically plotted and seen by all,
but tagged as "Pending" until they are vetted.  Users can change their
records at anytime as long as it is still pending.  A batch submission
process has also been developed.

(5)   OdonataDistributionViewer - this has been completely overhauled.  We
are still using GoogleMaps and GoogleEarth as our engine, but a completely
new application (like none I have seen) has been developed.  You can search
by taxa or geographic area.  It is world-wide in scope.  You can select to
view Google Maps or Satellite and choose to overlay (transparently or
opaquely) U.S. county boundaries on the map.  We are still facing speed
issues with this, but to overcome much of that, we have implemented a
"clustering" mechanism.  Basically, at broad zoom levels where there is a
lot of data, data is clustered instead of showing individual points.  You
wouldn't be able to discern the points anyway, so this helps speed things
up.  We are still looking at additional ways to improve speed with this
resource.  Records are indicated as clusters or points and pending or
accepted.  You can filter by the latter to increase data integrity.  We are
also now plotting data at their actual localities.  Dot Map data (indicated
as blue dots on the map) is plotted at county centers, but all other data is
plotted at the actual lat/long of collection.  This will allow users to
generate checklists and seasonality histograms for specific areas.  You can
also link to a specific species/geographic distribution and include them on
your own web pages.

(6)   Because OC has gone world-wide, we are now hosting a world catalog.
This is derived from several sources, but primarily from the Schorr et al.
list.  I have integrated Rosser Garrison's New World list into this however,
and have always defaulted to his list when there are discrepancies.  As a
result, you can now view/search either the World or New World catalogs.

(7)   I've added a "Resources" tab that will eventually contain all sorts of
useful information.  For now, there are subtabs that include the Taxonomic
Catalogs, OC Membership Directory, Taxonomic Notes, bibliography and Odonata
links.

(8)   There is now a tab for "Publications."  You can search and view the
DSA publications Argia and Bulletin of American Odonatology.  If you are a
current DSA member, all of these publications will be available to you.  If
you are not a member, then you will not be able to view the latest 3 years
of Argia or 3 volumes of BAO.

(9)   I have also added a tab for "Societies."  This has information
presently on DSA and the Odonata Survey of Texas.

Please change links on your web pages to reflect the new url,
http://www.odonatacentral.org.

We have worked hard to make the site compatible across platforms and
browsers. Not the following however.  Although the site looks gorgeous in
Safari, it appears that the Safari browser has an actual bug when dealing
with file uploads and there may not be a solution.  This has been reported
by others as well, basically it just hangs sometimes when trying to upload
files (which would apply to the record submission process on
OdonataCentral).

I welcome comments and feedback about the new improved site.  Please
remember OdonataCentral is a community-based server and project.  Its
success depends on users like you.  Thanks for looking at the new
OdonataCentral!

Catalogs, OC Membership Directory, Taxonomic Notes, bibliography and Odonata
links.

(8)   There is now a tab for "Publications."  You can search and view the
DSA publications Argia and Bulletin of American Odonatology.  If you are a
current DSA member, all of these publications will be available to you.  If
you are not a member, then you will not be able to view the latest 3 years
of Argia or 3 volumes of BAO.

(9)   I have also added a tab for "Societies."  This has information
presently on DSA and the Odonata Survey of Texas.

Please change links on your web pages to reflect the new url,
http://www.odonatacentral.org.

We have worked hard to make the site compatible across platforms and
browsers. Not the following however.  Although the site looks gorgeous in
Safari, it appears that the Safari browser has an actual bug when dealing
with file uploads and there may not be a solution.  This has been reported
by others as well, basically it just hangs sometimes when trying to upload
files (which would apply to the record submission process on
OdonataCentral).

I welcome comments and feedback about the new improved site.  Please
remember OdonataCentral is a community-based server and project.  Its
success depends on users like you.  Thanks for looking at the new
OdonataCentral!

I am not aware of the Italian specimen mentioned in the query.

To the best of my knowledge, the three largest "giant dragonflies" known
from the fossil record are Meganeura monyi from Commentry, France, wing
length estimated from a nearly complete wing to be 300 mm by Carpenter
(1943), Meganeuropsis permiana from Oklahoma, USA at 305 mm (nearly complete
wing, Carpenter, 1947) and Meganeuropsis americana from Kansas, USA at 330
mm (estimated based on two wing fragments, Carpenter, 1939).  Carpenter had
estimated the wing span of M. americana at "approxinately 29 inches (710
mm)" in his 1939 paper.  Based on the few complete specimens of smaller
Protodonata and on measurements of wing length vs wing span in modern
Odonata, I would expect the wing span for these 300-330 mm wing lengths to
be in the range of 628 to 698 mm - in any event, much less than a meter, but
pretty darned big anyway.  There is also still some question as to how
Carpenter estimated the 330 mm from his wing fragments, so I would prefer to
talk about these large Meganeuridae being in the 300-330 mm range of wing
length than to state for certain which is exactly the largest.

I can supply detailed references for anyone interested in having them.  I am
unaware of any really high quality photographs of any of these specimens
having been published.  A nice artist's conception of what Meganeuropsis
permiana might have looked like, see the color photo of Werner Kraus's
life-size model (model located at Lausthal-Zellerfeld University Museum) at:

Dear Dr Hamalainen,

My name is Alvin Francis from Singapore and am working with the Raffles
Museum in NUS and my boss Prof. Peter Ng is currently trying to contact
you regarding some survey work on Singapore dragonflies for a reservoir
project.  Not even sure if this is your contact.  Hope it is.

Thanks,

Dear Mr. Mauffray,

 

I have been searching for information on the largest known dragonfly found
in the fossil record.  Can you help me?  I have heard of one with a wingspan
over 1 meter from Italy but have not been able to locate a photo.

 

Thank you for your time.

1. Where can I purchase a copy of "A distributional list of world
Odonata" by Tsuda, Shigeru; 1986?

2. I'm looking for descriptions of the following dragonflies:
Lyriothemis euryidice Ris, 1909; Lyriothemis hirundo Ris, 1913;
Lyriothemis latro Needham and Gyger, 1937; Lyriothemis meyeri (Selys,
1878); Lyriothemis salva Ris, 1927.

I know what the original references are but am having trouble
finding them as I don't have access to good resources here; any help
with these is greatly appreciated.

3. I'm also looking for a diagram/photo of the secondary genitalia of
Lyriothemis biappendiculata (for information only).

P.S. I have a very poor, slow internet connection here; please keep
email replies to less than 500Mb.

Thanks, Nancy van der Poorten, Sri Lanka.

Hi all,
I am looking for quantitative descriptions of larval habitat for Ophiogomphus 
anomalus, Neurocordulia michaeli, and Helocordulia uhleri, 

particularly with respect to substrate (e.g., particle size) and hydrology 
(e.g. water depth, current velocity, flow regime). 


This information would be used to help design tailraces (outflows) at 
hydropower installations that would be suitable for these species. 


If anybody has any such information and is willing to share it, or point me 
towards any published or grey literature that I may have missed, I would be 
very grateful. 


Many thanks,
Rob Foster

Dear everyone,

The Mexican government is offering one year postdoctoral positions (subject to 
competition based on candidates' cv) to people who want to work with some 
Mexican 

scientists. This is an opportunity for those who would like to do research in 
my 

laboratory on the ecology and evolution of, mainly, tropical odonates but, 
depending 

on the subject (which I am open for discussion), may include other insects. My 
University is the largest in Latin America and among the top 100 Universities 
in the 

world. My research institute (my work place: http://www.ecologia.unam.mx/) is 
leader 

in several evolutionary and ecological issues so this is an opportunity for 
those 

people that want to continue within a highly academic environment. This is a 
highly 

heterogeneous multicultural place so that as long as the applicant speaks 
English 

(Spanish, obviously, much better) he/she won't have much trouble.

The offer has two deadlines:

22 October (2007) for those people starting from November (2007) to February 
( January (2008) for those people starting from March to August (both 2008)

Sallary is 20,000.00 Mexican pesos (approximate current exchange 1 USA dollar = 
11.09 

pesos) per month. The candidate should have got his/her PhD within the last 3 
years 

and have a number of publications in the area 

Please pass this message on to potential applicants. Those people interested 
please 

send me an email or call me (+). For further references about 
my 

research interests and publications see:

I have learned that I may be taking a work-related trip to the Lesser Antilles 
in late March (I know, rough luck...), and should it happen, I will be spending 
most of my time (10 of 12 days) on the island of Dominica. Was wondering if 
there might be someone on this list who could help me out with some information 
about the odonata in the area, or at least the ones that might be out & about 
at that time of the year? I made a quick search online, but had trouble coming 
up with much. 


Thanks.

Hi Group:
 
I am finally expecting the Color companion guide to the Damselflies of NA
any day now. I have been cross checking and labeling the shipping
containers.
Some of you ordered this book 2 years ago. Please let me know if you had an
address change. 
 
Also I have about 25 copies left of the DF of Central America. This will not
be republished.
 
For other books and envelopes please check the web site below.

Hello, all.

When writing about the Argentine Yungas book yesterday, it slipped my  
mind that there is another published book on odonates in the Neotropics.
-----
Lib�lulas de Mesoam�rica y el Caribe / Dragonflies and Damselflies of  
Middle America and the Caribbean
Carlos Esquivel
320 pages, 169 photos.
INBio: the Costa Rican Biodiversity Institute

For the first time ever, this book presents easy-to-read descriptions  
of the morphology, habitat, behavior, larvae, and geographical  
distribution of all the 16 families occurring here, plus accounts on  
the natural history of more than 75 of their commonest species  
illustrated with outstanding color photos of both sexes, some of them  
pictured for the first time.

Also included is a user-friendly Illustrated Key to all the families  
of this region and up-to-date, per country lists of all the species.  
Given the wide geographical distribution of the species treated here,  
both scientists and amateurs working with odonates in North and South  
America will also find valuable, novel information in this book.

Language: Bilingual, in Spanish and English.
-----
Note that only 75+ species are described, so in my opinion this  
doesn't qualify as a field guide to the species of the region (there  
are about 540 species), but it is certainly a worthwhile purchase for  
anyone wanting to know more about Neotropical Odonata.

Hello, all.

You'll hear more about this book, but I just wanted to mention its  
existence and recommend it.

Dragonflies of the Yungas/Lib�lulas de las Yungas (Odonata), by  
Natalia von Ellenrieder and Rosser Garrison, has just been published  
by Pensoft (a publisher in Sofia/Moscow). This 116-page book, in  
English and Spanish, contains all 102 species of the cloud-forest  
zone in the northern Andes of Argentina. Almost all are represented  
by color photos, the first ever published for most of the species,  
making this the first field guide to Odonata anywhere in the New  
World tropics. It's a handsome and informative little book with many  
line drawings of structures to facilitate identification, along with  
the photos.

The price is 25 Euros ($34 US), and it can be ordered at http:// 
www.pensoft.net.

You'll hear more about this book, but I just wanted to mention its  
existence and recommend it.

Dragonflies of the Yungas/Lib�lulas de las Yungas (Odonata), by  
Natalia von Ellenrieder and Rosser Garrison, has just been published  
by Pensoft (a publisher in Sofia/Moscow). This 116-page book, in  
English and Spanish, contains all 102 species of the cloud-forest  
zone in the northern Andes of Argentina. Almost all are represented  
by color photos, the first ever published for most of the species,  
making this the first field guide to Odonata anywhere in the New  
World tropics. It's a handsome and informative little book with many  
line drawings of structures to facilitate identification, along with  
the photos.

The price is 25 Euros ($34 US), and it can be ordered at http:// 
www.pensoft.net.

Dennis and group:

 

I have secured a unused copy of the Dragonflies of North America that was
returned by a book dealer to the publisher. I had to pay a premium for it.
In order to make the same profit margin as before, I would need to get
$200.00 for US delivery address (S&H included) or $210 Canada/Mexico, or
$220 elsewhere. I only have one copy. first come first served. PAYPAL
preferred (with 3% surcharge)

 

The Color companion guide to the Damselflies of NA should be here within the
next few days. They will ship as soon as I receive them.

 

I still have about 20 copies left of the dragonflies of Central America.

 

I have a lot of Dragonflies through Binoculars available

 

Poly and Cellophane envelopes also..

hi All
 
Three buddies of mine & i have planned a low-budget land &  pelagic trip to 
California for Sept. 21-29, 2007 (departure for home is very  early am on the 
30th), mostly for birding, but at least 2 of us have a great  interest in 
odonates & butterflies as well (i personally monitor for birds. D-flies, & 
B-flies 

at a forest preserve near where i live in Warrenville,  DuPage Co., Il; i 
also lead nature-walks at various preserves in the  Chicagoland area to share 
knowledge & stimulate interest in these, as well  as in other fascinating 
creatures)
 
never having sought these in California before, we are hoping for some  
helpful info from 'those in the know', especially concerning the endemic & 
western 

dragonflies & damselflies (also b-flies) species that can be  found on those 
dates in, or at least relatively near the areas that we are  planning to 
visit/sleep, as there is a little flexibility in a few of the days, for seeking 

critters other than the avian kind (we also have interests for western mammals, 

reptiles, amphibians, etc.)
 
our itinerary is mostly laid out with this schedule pretty well set &  
centered around the birds that we hope to see, & for which we have abundant 
info 

from the most recent birding guides:
 
Friday, 9/21: arrive in San Diego; visit Cabrillo National Monument/ Pt.  
Loma, Mission Bay, La Jolla, Torrey Pines, & Mission Trails; camp at  Kumeyaay 
Lake Campground
 
Sat., 9/22: continue time at Mission Trails, then on to Tijuana Slough/  
South Bay/ Imperial Beach/ Border's Field S.P., & later the Laguna  Mtns
 
Sun. 9/23: visit Anzo-Borrego, then the Salton Sea, & then hope to find  a 
convenient campground
 
Mon. 9/24: most/ all of day at the San Jacinto Mtns, camp at Hurkey Creek  
County Park
 
Tues. 9/25: continue in the San Jacinto Mtns, & then on to Ventura,  camp at 
McGrath State Beach
 
Wed. 9/26: visit Santa Cruz Island for 3-6 hours; drive to Oceano Dunes  SVRA
 
Thurs 9/27: visit Morro Bay & Big Sur; stay at Monterrey Hotel Super  8
 
Fri. 9/28: Monterrey Pelagic trip; camp somewhere north of Monterrey
 
Sat. 9/29: an open day; options: Pt. Reyes, Mono Lake/ Yosemite, hotline  
chasing, etc. ? Stay in or near San Jose from which we fly out of very early am 

 
we realize that this time of the year is far too late for most species, but  
any help would be much appreciated--abundant thanks in advance
 
gary moore
 
p.s. i have the 2 Cal. books by Tim Manolis & Kathy Biggs on  D-flies
