From: Adolfo Cordero Rivera <adolfocordero AT mundo-r.com> Date: Thu, 4 Feb 2010 16:14:50 +0100 Dear colleagues In the last years several voices have argued that the "Impact factor", "H-index" and many other quantitative assessments of scientific quality have had a tremendous negative effect on Taxonomy. I am not a taxonomist, but I have suffered when participating in committees to select new researchers in Spain, and discovered the narrow mind of otherwise bright scientists: taxonomic works, when published in journals not included in the "Journal Citation Reports", were valuated as "ZERO", even 50 papers, or several monographs were simply ignored, because they had very little "impact". This perversion of science valutation is disgusting, and in some countries (for instance my own) has caused the dissapearance of entomological journals with more than 100 years of history. I recommend reading this essay, free to download in pdf: Boero, F. 2010. The study of species in the Era of Biodiversity: a tale of stupidity.

As a result of a posting I received a picture of Sympetrum nigrifemur (often also adressed as S. striolatum nigrifemur) from a British photographer for ID. The photograph was taken - if I remember right - during December 2001 in Lanzarote, Costa Teguise, but unfortunately this mail (with the photographer's name and the exact date) got lost over the years. Well, at this moment I am compiling all available records of Sympetrum nigrifemur from entire Macaronesia - for a planned review paper on ecology and distribution of this sp., together with R.Malkmus, and for an according talk at the 1st European Congress of Odonatology in Porto next July. However, the picture that reached me during early spring 2002 is still the only record I know from the island of Lanzarote; hence, dear British photographer, please contact me if you read this! And, of course, any other unpublished records of the sp. from the Canaries, the Selvagens or Madeira are highly welcome, in order to get a good overview on the phenology. All records I receive will of course be listed with full reference to the observer's name.

I'm nearing completion on the manuscript of my eastern odonate field guide, and I'm pulling together known flight seasons for Odonata in all the eastern states and provinces. I have the information in all the publications in Bulletin of American Odonatology, as well as books on several states and a few websites that seem up to date. I have compilations so far for IA (BAO), MO (atlas), IN (book, Anisoptera only), OH (BAO, books), ME (website), MA (book), CT (BAO), NY (BAO), NJ (BAO, book, website), LA (BAO), MS (BAO), AL (BAO), GA (BAO, book), and FL (BAO). Some books are for smaller (Algonquin Park) or larger (North Woods) areas than the province and state level I would prefer, but I might use them if I can find nothing else. So I'm wondering if any of you out there have lists of flight seasons you have compiled for your state or province, and if you would be willing to let me use them. This would include updates to published works, and I suspect there is scarcely a region that has not had these dates updated in recent years. I am expressing flight seasons at the month level, so a known flight season of April 19-August 7 in Kentucky will be expressed as KY Apr-Aug, as I have done in my western guide. Thanks!

I photographed the behavior at least once, and I seem to recall arriving at the conclusion that it was trying to dislodge pesky fecal material that was clinging to the tip of the abdomen.

Interestingly, I have seen behavior similar to this before, but not quite as extreme as you seem to describe in a couple of species, actually. It seems to be easier for dragonflies with longer abdomens. However, this year, I was able to capture the movement on video tape. It was the first time I saw a Libellula vibrans actually appear to touch it's genital area. The wild thing is, as I started to check it out frame by frame -29.? fps something very interesting was happening. Even though the abdominal bend is done once, the dragonfly actually touches the genital area 2 or three times in rapid succession with the cerci/anal area. In fact, it is so fast, that when you are just looking at the video segment as a whole, you don't see the action. I can hardly wait to see your photo! I am trying to put together a whole tape for you guys to see soon - so you can see the action of this and a close-up of a Lv exercising his penus(?) correct term? Martha Edwards Smith P.S. Also I've got some interesting action when a Pachidyplex longpennis presents with its abdomen vertically. Its genital area popped out farther exposing it more openly to the bush branches. Where the females might see it, possibly??_______________________________________________ Odonata-l mailing list Odonata-l AT listhost.ups.edu https://mailweb.ups.edu/mailman/listinfo/odonata-l Subject: Re: Fwd: interesting behavior From: June Tveekrem <damselfly AT southernspreadwing.com> Date: Mon, 25 Jan 2010 18:58:44 -0500 _______________________________________________ Odonata-l mailing list Odonata-l AT listhost.ups.edu https://mailweb.ups.edu/mailman/listinfo/odonata-l Subject: Fwd: interesting behavior From: Dennis Paulson <dennispaulson AT comcast.net> Date: Mon, 25 Jan 2010 13:13:52 -0800 I am sending one of a series of photos of this Anax junius flexing its abdomen, to ask if anyone has seen this and/or has any idea of its significance.

To dryed specimens, which are not in entomological pins, or broken parts of pinned specimens, we used cellophane triangles, but I'm need more triangles. Does anyone know of a supplier of those triangles? In the pass we made the triangles in the departament, buy we would preffer buy it now. The triangles should be transparent, not traslucent, to avoid specimens damage with manipulation. Any ideas?

This species has such a thin club that the females are quite commonly considered something other than a Gomphuurus. Many midwestern specimens are mistaken for graslinellus, which perversely has a broader club in the female!

In particular, I can't find the "unicorn-like upright point at the middle of occipital crest" mentioned in Dragonflies through Binoculars. Can anyone identify it? Incidentally, I took these photos at the Headwaters of the Mississippi, near a little bridge between the gift shop and the Headwaters marker. The flow rate at this point is at least 30 tourists per minute, but this dragonfly sat right at the edge of the path and ignored both the foot traffic and my camera. With that black patch in its left eye, I imagine it might have been partly blind, but it took no notice of me even when I came in for a closeup on its right side. Maybe the dragonflies around there get used to people. I often see a greater variety of species at the Headwaters than in quieter areas of the park, even though children are constantly splashing around in the river. _______________________________________________ Odonata-l mailing list Odonata-l AT listhost.ups.edu http://mailweb.ups.edu/mailman/listinfo/odonata-l Subject: Re: ?'s About The Effects Of The Water Table Level onDragonfly Populations From: "T Donnelly" <tdonelly AT binghamton.edu> Date: Fri, 4 Dec 2009 23:24:44 -0500 Interesting observations and ideas. I think you mean water levels. Water tables are underground and respond very slowly to flood events. The most important thing about water tables is that they supply slow ground water discharge to rivers in all but the most arid of terrains. Eads, who was a famous bridge builder, also made some marvelous observations on flooding. Before building the bridge across the Mississippi at St Louis (in the 1800's) he surveyed the site extensively. He was especially interested in flooding, so he made a rubber suit and actually walked on the river bottom during a flood! What he found was that the river bottom deepened through bottom erosion far more than the surface went up. His bridge never was destroyed, but it would be interesting if he hadn't taken his perilous walk. The major effect of flooding on dragonflies seems to be that benthic larvae are taken right out, along with the finer sediment, leaving an "armored" bottom covered by cobbles, and highly unsuitable for most burrowing odonates. At Binghamton in 2006 we had our "500 year" flood, and the benthos has still not recovered. Other than that, there will be temporary pools on the flood plain, where the soil tends to be very clayey with much organic matter. How long these pools will persist is a good question. Farmers tend to destroy them. Floods are increasing, partly possibly because of "global warming", but maybe more due to centuries of poor land practices, and channelizing, and building unwise dams, and . . . I could go on and on. We very much need observations. My most recent involves Ophiogomphus larvae on the upper Hudson, where we have a probable new species among six old species. This year was one of high water, though not proper flooding. Larvae were very difficult to find among the cobbley bottom, and fine sediment was downright scarce. So, keep it up! This is an important area of investigation.

In 1999 Hurricane Floyd hit after some minor ones went through. We live near Rocky Mount, NC. In the distance, you can barely see the wake of a jetski going down Hwy 301 (he was looking for a place to buy diapers). The red arrow to the right points to the area of water covering Tarrytown Mall, once, the largest mall (one of the first enclosed) east of Greensboro, NC (that included the Raleigh/Durham/Chapel Hill area - an amazing thing - considering the growth of this area since the late 60's). In addition to all of the rain water of Floyd (20 inches at least in one day), the Tar River usually crests about 3-or more days after serious rainstorms. Consequently, the water was that high or higher for a week or more. It was crazy! Unlike New Orleans and Louisiana, we have been victims of hurricanes on a regular basis until the past two years. And while the severity of this one shocked all of us, we were "somewhat" prepared. Here is a little bit more information about my ?'s. The problem is that I realized after seeing our neighborhood stream that up until now has flooded every year since I have lived here (30 years), at still such a low level after quite a bit of rain this season and a decent amount of rain. You see, in addition to the established micro-habitats of particular dragonflies, our species diversity depends not only on those new species that fly through and oviposit there, but also the flow of the stream and its shifting of nymph populations from the swampy areas deep in the woods. It all of a sudden scared me, have all of my dragonfly experiences been the result of an ecological fluke (unusually high water table)? Thank goodness, I had the opportunity to record it on film - essentially - from the first 35 mm SLR pictures in 1998 - of "Mr. Dragonfly," even through the encephalitis and the after-effects (I couldn't communicate or walk very well and although I could hold a camera, it was pretty shaky) to the move in 2001 to the digital Hi-8 Handycam which I have used ever since. Does anyone know anything about the effects of mostly clay-based soil area and the biological life it might support, as opposed to areas composed of more decomposing leaves and soil? Besides the sunlight shift and possible microbe population the one really important factor is that of gradual "reverse" erosion. When we first put the pool where it is, we deposited a great deal of excavated clay in the area. In addition to the clay somewhat washing into the newer area the dragonflies use for oviposition, the original area has some areas of sand that leaked from under the pool and decomposing leaves that have fallen from the trees. I do rake it out every year and walk through the space barefoot to leave indentations for collecting puddles of water that the dragonflies use for oviposition, but I can tell that the composition is changing, because my feet aren't sinking in as far as they once did. This has reminded me of the story I once heard in one of my anthropology classes about how after WWII, we had he great idea of trying to help the Asians cultivate their rice fields by introducing tractors. I was disastrous, the tractors broke down the layer of clay that kept the moisture levels just right for the production of rice. Often, when I see the dragonflies hover above the ground before they leave ovipositioning area, I wonder: * Are they looking to see how long it takes the H2O to percolate? * Are they checking for predators? * Are they sensing the H2O temperature? * Are they looking for nymphs of the same species? * Can they tell from the light reflecting from the insect/animal eyes what species are under the water? * Are they cruising for the right eye reflection coming from under the water so they can come back with a female for oviposition? If you think I'm nutty, just check out my albums of Calopteryx maculata with the white reflective (ambient Light)/luminescent substance near the end of the videos, you can see the frog's eyes almost come up to the surface of the water and shortly after the Calopteryx flies off. Sorry about the experimental nature of the videos-I was trying to help you see the behaviors and extended the frame times to a few seconds-if you can be patient and look, you'll see them and the presentation of the damselfly's tail in reproductive behavior-I would think. As soon as I can, I will try to upload in much better quality to my YouTube channel-"scldrgnfly" - but for now, you can try: www.marthasmith.neptune.com you might have to allow a pop-up, or add an add-on to get access to the site-a lot of people have had difficulties. * Or do the nymphs produce a certain chemistry distinctive to their species I think I could go on, but because I have had the advantage to film a narrow stream for years, it seems quite positive that they do have a specific habitat memory, but with one of the advantages of high trees to scope out more advantageous areas, too, for species habitat diversity in times of drought, etc. Now scoping out the females in the trees, I'll leave for another missive. On Monday, I am going to start tracking things down and see if the Entomolgy Department at NC State and the Department of Natural Resources/AG Extension Offices can help me.

Each year, about this time, I begin to contemplate how many, if any dragonflies will populate our habitat during the next summer. In the past 2 years, the habitats that I watch have shrunk so because of our drought situation. I actually think it will be better in 2010, though. We seem to have had more steady rain periods, even if it hasn't been as much as past years. What I do worry about, is if our dragonfly population over the past years was an anomaly caused by the greatly increased rainfall due to the number of hurricanes in the 90's. During Floyd, we reached the 500 year water table. It would be a shame if this were so. A very interesting observation is this: Our trees are very tall, almost 80 feet, mostly gum, oak, pine and a huge magnolia. The very tops, where some of the dragonflies perch, had what appeared to be quite a few dead branches. In fact though, many of the branches must have just gone into a dormant state as a result of our severe droughts, because this year, with somewhat steadier rains, they have leafed out (after 2 years), making it a bit more difficult to film the dragonflies at their highest perches, where they seem to select the most optimal habitats for populating - or - they seek partners seen or sensed from great distances . How strange to be so positive about this, but after just allowing myself to film one habitat for over 10 years (for a controlled method of observation), I could *almost* say, I know the branches on my trees, in addition to the insects and animals that pass through, and those that stay a while. Actually, I only know the ones on which the dragonflies perch most frequently - and - I cheat a bit, since during that time, I have perused 100's of feet of film over and over again, frame by frame to see what I see. While we are all victims of the periodic "Optical Delusion," and, obviously, we all need to be careful of this, it's difficult to argue with frames that are matched perfectly with the exact - same - visual marks. Getting back to clarifying my point, could this period of great population be over? How often does a particular water table reach the 500 year level, and how close does it come to that level and for how long, before actually reaching it? And, how long does it take to go back down to a mean level? Have there been any studies on this?

Substance Cross Species During Reproductive Period ?'s From: Martha Smith <scldrgnfly AT gmail.com> Date: Sat, 21 Nov 2009 18:51:21 -0500 Here is my latest attempt to share a Nature/Wildlife Video on YouTube. It isn't dragonflies yet. I am saving them until I have gotten better at editing. I really want them to be special for you all' It isn't perfect. Big Grasshoppers at The Smithsonian First Edit.wmv http://www.youtube.com/watch?v=1fg2sRMx560 Near the last few minutes of this tape, there are grasshoppers (the females?) with highly "reflective" substance on their anal openings, which they seem to be "presenting" for reproductive attraction, especially after the substance increases in volume and reflective intensity. Has anyone ever checked these substances for any enzymatic activity?(IE. the substance which is visible on the dorsal/anal side of the abdomen which the Calopteryx maculata seems to be presenting for attractive reproductive behavior on my www.marthasmith.neptune.com site) Even though the one grasshopper goes into a very dark corner and you can just see its glowing anus (it isn't producing much yet, and it is straying from the very active main group, so I would guess it isn't ready for "Center Court"yet), it's very dark, and there is ambient light. Now, one might say, why waste this much action on insects? It is precisely the time issue for this behavior. They don't have much time at all to preserve their species. -And -without "bugs" (bees (Most important-for us) we wouldn't have a basic fuel for food/energy and an incredibly ubiquitous means of population control, most effectively, on the microscopic level. Unlike the pruinescent coating of the male dragonfly exhibited during the whole reproductive period, it appears to me that the female has a more "time specific" indicator, indicating an optimal fertilization point. Regardless of the reflective/luminescent(?) nature of the substance or the action, I find it interesting that light (reflectivity) and color, in addition to specific attractive behavior and substance (matter/pheromones) seems to be universal in the animal kingdom--IE. female Hamadryas baboons red bottoms, slugs swinging from the trees intertwined in a vine of their own mucus, the Calopteryx maculata (I think)-- and possibly, the grasshoppers. As far as light (reflectivity) and color and the HIGHLY reflective nature of some of their joints go - go back and really look at their joints-they are almost glow-bright in some instances; it makes one wonder about the fact that the Japanese consider the nape of a woman's neck (cartilage and bone) a highly attractive place . How much are humans affected by Infrared and ultraviolet light without the particular visual awareness insects seem to have? Have we lost the consciousness of this very real sensitivity due do the greatly increased magnitude of our intellectual input resulting from the technological success of our brains and our highly accessible opposable thumb? Or are we simply attributing the insects' seeming awareness to them soley because we are able to observe these things and as humans we have a need to apply action to awareness? Or, is it our interminable ego-centric nature as humans to constantly attribute truly anthropomorphic characteristics to the animal kingdom, such as the basic activity of attraction and the simple ability to be aware of this activity? Without attraction, whether reproductive or predatory, where would all of us be? Funny thing is, while we interpret what we see in our terms, they're human interpretations. And- if you are reading this on a computer, you can bet you are one of us. As humans we cannot escape our anthropomorphic roots, as unbiased as we might think we are. Seriously though, I do think there are some interesting observations to be had. At the very end of the tape, is another type of insect/grasshopper(?), that is WILD--you have to look carefully for their cone-shaped heads and eyes-they are hanging upside-down--quite bizarre.

From: Ylightfoot AT aol.com Date: Thu, 12 Nov 2009 00:34:15 EST Hi guys: This outfit is apparently in my backyard, so to speak. Here is a review of the new venture which just came out in today's Sacramento Bee: _http://www.sacbee.com/livinghere/story/2317405.html_ (http://www.s acbee.com/livinghere/story/2317405.html) I hope to try this stuff out when it becomes available, and will report the results of my "research." I know it is a ways to travel for many of you (especially in the northeast), but Sacramento can be a lot warmer and sunnier place to visit, even in January, than is New England, so you are welcome to join me on this "field trip." Just drop me a line. By the way, the Sacramento Brewing Co., whose demise is mentioned in this article, will be sorely missed locally.

No sooner than I sent you a message about your purple Orthemis macrostigma photo, I got your photos of red Orthemis. Let us see what you got. Ok. The first one is what I have determined to be Orthemis schmidti based on my research. The other 3 are not Orthemis. They appear to be the smaller Brachymesia furcata species, but the cerci do not look as upturned as ones I have seen before. Maybe Dennis Paulson can help as he has seen lots of them and he will have photos of Brachymesia furcata in his upcoming new book. Hope this helps, Michel. Let me know if you have any questions. Talk to me later! Aloha nui! Jerrell P.S.

From: "J J Daigle" <jdaigle AT nettally.com> Date: Mon, 9 Nov 2009 11:39:41 -0500 Aloha, Michel! The forewing venation appears to be black. In this case, I would call it the Greater Antillean form of Orthemis macrostigma. Ultimately, I believe, the end result name of the dragonfly in your photo will be Orthemis ferruginea when I finish collecting enough empirical data from specimens of the Orthemis ferruginea complex in Central America, the Caribbean, and South America. I have seen old museum male specimens from Haiti, DR, and Jamaica of what appears to be Orthemis ferruginea. However, I have never seen a confirming specimen of a female Orthemis ferruginea from these countries. Someone needs to go to these countries and catch some females. That would be a big help! Dennis did a lot of work in sending you links and background info on the Orthemis ferruginea complex and we thank him. You mentioned that some of your photos of red Orthemis from DR look at lot like Orthemis schmidti. I need to look at them, but I am pretty sure it is O. schmidti. If you follow the key in DeMarmels's (1988) paper, specimens of the red Orthemis from the Caribbean key out to Orthemis schmidti. I cannot find any structural differences or significant color differences between Caribbean and South America specimens. DNA work is also being done now on the entire Orthemis genus to see the relationships between Caribbean, CA, and SA populations of Orthemis plus to see which species can stand alone genetically. Hopefully, it can help resolve the issue. Dennis mentioned that he believes the Caribbean Orthemis schmidti may be or is a new undescribed species. I am not sure who is describing it as a new species unless it is Nick Donnelly. He has been working on the Caribbean Orthemis for some time way before me. Michel, I hope this helps. Let me know if you have any questions, and try to catch some red Orthemis schmidti or purple O. macrostigma the next time you see some. Thanks! Talk to me later and keep those photos coming!

Photos 154-156 are of a female Brachymesia furcata, another common red neotropical species. It is smaller than the Orthemis, with a somewhat different abdomen shape and quite different wing venation. The black marks on the abdomen tip are in fact symmetrical, a little bit of a dorsal stripe on those two segments that is often present in B. furcata. Female furcata can eiher be plain brown or with a quite red abdomen.

But read the account of Orthemis in that book for more information. O. macrostigma was listed as a synonym of O. ferruginea, but it is not. It is a valid species restricted to the West Indies (it may occur locally on coasts surrounding the Caribbean, but that is still being studied). Meurgey, F., and J. J. Daigle. 2007. New status for Orthemis macrostigma (Rambur, 1842) from the Lesser Antilles (Anisoptera: Libellulidae). Odonatologica 36: 71-78. O. ferruginea was thought to be the only species of its genus over a huge range, and now we know there are quite a few more species in this group. It is much more complex than might be apparent at first sight. De Marmels, J. 1988. Odonata del Estado Tachira. Rev. Cient. Unet 2: 91-111. Donnelly, N., 1995. Orthemis ferruginea - an adventure in Caribbean biogeography. Argia 7(4): 9-12. Paulson, D. R. 1998. The distribution and relative abundance of the sibling species Orthemis ferruginea (Fabricius, 1775) and O. discolor (Burmeister, 1839) in North and Middle America. Int. J. Odonatol. 1: 89-93. O. schmidti is a South and Central American species that probably does not occur in the West Indies but is replaced by the undescribed red species. Paulson, D. 2001. Orthemis schmidti is a widespread species. Argia 13 (3): 24-25. O. sulphurata, described from western Ecuador, is also very similar and may be much more widespread. There is ungoing, unpublished research by several investigators on this confusing complex, which can be very difficult to distinguish either in life or as specimens.

Hello, Michel. The purple species in most of the West Indies is Orthemis macrostigma (no English name). There is also a red Orthemis in the Greater Antilles that is at present undescribed. O. ferruginea is a purple species widespread on the American mainland that is only locally distributed in the islands near Florida (Cuba, perhaps Bahamas). Present-day books don't provide information on the common West Indian species. There are also other bright red species in the Dominican Republic, but they would look rather different from an Orthemis.

This is because if you have only one pond with fishes and one fishless pond, there is no replication. Any difference you might find between ponds could be due to the fishes but also to anything else that happens to be different between the ponds.
