I purchased it in early 2006 and like all modern electronics it was quickly discontinued and replaced by a newer model. The main reason I chose this scanner was its portability since I've been traveling a good deal to collect dragonflies. It also retailed below $100. I'm sure there are better scanners available. I would guess a full size scanner with a brighter scan element may provide better depth of field but I have not tested any recently. Here's a resized scan: http://homepage.mac.com/edlam/dragonimages/P_superbus.html Here's a crop of a scan at 1400dpi where you can see the limits of the depth of field: http://homepage.mac.com/edlam/temp/C_adnexaMtop.jpg And a crop of the same specimen lateral: http://homepage.mac.com/edlam/temp/C_adnexaMside.jpg I'd be interested in what you decide on as I will probably need to replace this scanner eventually.

I had pinned specimens and pinned then upside down using styrofoam blocks to keel the head of the pin off the glass. Unpinned Odonata could be laid flat on the glass, but the legs could not be shown. I have often thought that if a fine hole could be drilled in the glass, the pin could slide into the hole and the legs and wings might both be in focus. Just a thought.

I didn't have every lake/year combination, but many of the lakes were trapped in all 3 years, and overall it was one of the largest such field surveys of emergence I know about.

From: "O'Brien, Mark" <mfobrien AT umich.edu> Date: Mon, 14 Apr 2008 09:49:33 -0400 Well, you said flight mode, and then talk about perching... What you are asking has more to do with reproductive behavior and feeding and less to do flight modes. The Corduliids, Macromiids and Cordulegastrids are not considered perchers, but more like "hangers" -- same as a lot of Aeshnids. If you were to see any of these groups in flight, you would see that they rarely alight except when resting and in inclement weather. Mark Mark F.

We would like to investigate the acoustic properties of a few representatives of this Family of insects. This is, how their body (shape, texture, material,...) influences the refraction of sonar waves emitted by bats. To do this, we would require some specimens of Libellulidae looking more or less like the ones our bat is feeding on (ws 6-7 cm, boylength 4 cm). Our group is located in Europe, Belgium. Therefore it's not clear at all how we could obtain samples of Neotropical insects for our studies. My searches on the internet and the posting to the ENTOMO-L list did come up with only a few pointers that have yielded no concrete results so far. Therefore I'm now trying my luck on this list. I've found some vendors of dried insects. But most of them do not sell Libellulidae. And I have had no response from those who do when I contacted them. So my question to the list is basically this: Does anybody know how I could obtain specimens of Libellulidae that have a wingspan of about 6-7 cm and a body length of 4 cm. Maybe someone has some old material lying around with which he or she is willing to part?

From: Marquette_Crockett AT fws.gov Date: Thu, 27 Mar 2008 12:50:11 -0400 Hello, My name is Marquette Crockett and I am a wildlife biologist at Canaan Valley National Wildlife Refuge in Davis, West Virginia. Canaan Valley is an incredibly unique high elevation wetland complex (and a great place to visit - FYI). For the past three years or so our refuge has participated in an odonate atlas project sponsored by West Virginia Department of Natural Resources. To date, the survey has focused primarily on adult odonates. We have documented over 40 species from the refuge and hope to document many more. We have been lucky enough to have a student volunteer on the refuge this summer. We hope to have her (along with myself) focus on expanding our knowledge about which odonate species are found on the refuge. I hope to collect larval specimens this year (especially in our numerous stream, seepage and bog habitats). I am looking for several pieces of information. First of all, I am looking for qualified "experts" that would be willing to identify the specimens that we collect and give us a species list. We have no funding for the project, but the specimens could definitely be kept as a part of a museum collection. I was also wondering if there are any standard texts to assist with basic specimen identification (so we can at least keep from overcollecting the same species again and again). Lastly, I was hoping to find out what preservation technique is most used for odonate larvae. Any information that you could provide would be greatly appreciated. I'm fairly new to the world of odonates, but hope to work hard to make them a part of the refuge's conservation and planning efforts.

There are numerous examples to the front and top of heads. The occipital spines of several genera are commonly broken off, presumably during tandem pairing. This is definitely an "ouch" experience for the male! The eye damage reported by Dunkle for Hagenius occurs also on other North American gomphids. I have seen good examples in Gomphus adelphus, for example. In Hagenius it appears to have been caused when the male epiproct which is loosely "locked" in front of the female poct-ocellar tubercles slips off and gouges the eyes. Certainly measurements fit this explanation. I guess that this sort of damage will be found to be somewhat common. But the damage I report in Ophiogomphus is far from incidental. I believe it is found in the majority of mature females. Teneral specimens, of course, have the rear of the head quite unmarked and pristine. Most mature females have the rear of the head quite scraped and squeezed, which I guess is caused by the male cerci. By the way, I have long admired Pinhey's paper on this subject, which I do not recall includes damage features.

If they are on Ophiogomphus, I assume they are on other genera. When you look at the hooks and bumps and spines on the appendages of many male odonates, it's not surprising that there is female head damage, especially when you think they have to hold on pretty tightly when they're flying around in cop. I suppose all the little bumps and spines under the cerci of many libellulids are sort of a nonskid apparatus, but do they leave marks on the females? The cerci of species such as Arigomphus cornutus and Octogomphus specularis look like lethal weapons. Do they leave bigger scars? Philip Calvert described in detail the hooking up of the complicated appendages of male Epigomphus with their females (Calvert, P. P. 1920. The Costa Rican species of Epigomphus and their mutual mating adaptations (Odonata). Trans. Amer. Ent. Soc. 46: 323-354.). At the same time, as it may not be in the female's best interest to have her head pierced, you'd think her cuticle would be strengthened at those points. Or is there some positive consequence of the "mating marks" on females, for example those on the eyes of aeshnids that Sid Dunkle described (Dunkle, S. W. 1979. Ocular mating marks in female Nearctic Aeshnidae (Anisoptera). Odonatologica 8: 123-127.) and can be found on a variety of female anisopterans? To me an interesting question is why cerci should have spines or hooks on the dorsal surface, which presumably doesn't contact the female. Does the projection on the top of the cercus in something like Epitheca canis serve any function? Does it touch the female somewhere? Mark McPeek is doing all this interesting scanning of cerci in damselflies, but I think someone should be looking more closely at the situation in anisopterans as well. Mating pairs of anisopterans should be collected and somehow preserved in tandem, even with the female's head detached from her body. As the connection is only on the head, it might be easier to understand than the perhaps more complex connection of male zygopteran appendages with both the female prothorax and mesostigmal laminae. And we need a good assessment of the sensillae that are presumably present in the female to tell her that the male appendages "feel right." When I see the amazing amount of variation in the complicated appendages of male odonates, I often wonder how those of each species could possibly hook up to the female's head or thorax and whether the varied shapes are a consequence of selection for reproductive isolation or a varied response to holding on tightly. Within a genus of libellulids, the appendages are often fairly similar, but then they may be quite different in another genus. Why? Some adaptations seem obvious, like the long, simple cerci of male Tramea, used for quick reattachment to the female after each oviposition dip. Most others aren't so obvious.

In fact in most of natural compounds left handedness seem to be most common. In fact one isomer which rotates light in one particular direction is most active than the other or the mixture of two even as drugs. But, I was interested in knowing how they perceive and what kind of information their brains process! Of course it is hard to understand what birds or beasts are thinking. But I did some BIOSIS and web search, here I came across this website http://polarization.com/index-net/index.html which explains how polarized lights are used by insects. This is quite a fascinating website. Anyone interested in polarized light should see this.

Insect vision ought to be less susceptible to the blinding glare from a planar source (such as a window pane), because the tubular facets (ommatidia) radiate from the interior of the compound eye, pointing in many directions. Only one facet at a time should capture the glare, or for that matter gaze at the sun or the moon or a bright star. A simple night-navigation routine for an insect brain might read something like "keep the moon in ommatidium # L-9355". I don't know what benefit accrues from being able to detect polarized light, but, just by the nature of the information that polarization conveys, I would expect it to be related to navigation or some kind of orientation-response. -Geo -- John & Sue Gregoire Field Ornithologists Kestrel Haven Avian Migration Observatory 5373 Fitzgerald Road Burdett, NY 14818-9626 "Conserve & Create HABITAT" http://home.att.net/~kestrelhaven/ _______________________________________________ Odonata-l mailing list Odonata-l AT listhost.ups.edu https://mailweb.ups.edu/mailman/listinfo/odonata-l Subject: Re: Best current text on Odonata morphology/taxonomy?

From: "Nick and Ailsa Donnelly" <tdonelly AT binghamton.edu> Date: Fri, 21 Mar 2008 13:27:37 -0400 It is pretty difficult to beat Tillyard (1917) for morphology, and for a lot more. My copy is close at hand at all times and is fairly dog eared from much use. Asahina's 1954 Epiophlebia book is more detailed and goes into things like muscles. It is based on a single taxon, and an odd one at that, but there is a huge amount of comparison with other damselfly and dragonfly taxa, so it is more generally useful than it seems at first glance. Chao's 1953 "Morphology of Onychogomphus ardens" is pretty thorough for gomphids, but less help for other odonates. Snodgrass's 1954 "The Dragonfly Larva" is very useful. Wing venation is a mess. The most commonly used scheme in most manuals is the old Needham- Comstock scheme, which in spite of some glaring problems is the most commonly used scheme general manuals, even though the authors presenting it almost always point out its problems. So one needs to learn this terminology in spite of the problems with it. The Tillyard - Fraser scheme is better but has been used less. A more recent scheme by Edgar Riek and Jarmila Kukalova-Peck is better still, but is used by very few workers. The obstacle here has been to try to relate odonate wing veins with those of other insects, which is surprisingly contentious. Many regional manuals have good introductory morphology sections. The North American dragonfly (Needham, Westfall, and May) and damselfly (Westall and May) manuals have fairly thorough morphology, using (natch . . .) the Needham Comstock scheme. The Australian Watson et al manual (With Tillyard Fraser terminology!) has a good morphology section very similar to Alex O'Farrell's section in the Insects of Australia (a huge book likely to break your foot if you carelessly drop it, and a book, by the way, which is still to me the best introduction to all insects that I have seen. Happily I have been able to avoid dropping it.). For taxonomy you will have to punt. I still like Fraser's 1957 Reclassification of the order Odonata as a useful place to start, although I believe less and less in the details as the years goes by. I find that I don't much agree with the various modern groupings, all of which have ardent supporters and still manage to disagree with each other. Someone has to be wrong, and it is not certain anyone is correct. It is still amazing to me how much the moderns still agree with Fraser even though they dismiss him as an old arm waver. Lieftinck, arguably the most illustrious odonatist in the 19th century, never really got heavily involved with taxonomy above the genus level. Maybe there is a lesson for all of us. If you are really into phylogenetic relationships, you should take a look at Grimaldi and Engel's magnificent (and heavy!) 2005 book "Evolution of the Insects". It is heavy on fossil insect studies and is magnificently illustrated. Overall, Jill Silsby's recent book "Dragonflies of the World" is an extremely useful place to get acquainted with the individual families. If you are not a world traveler and haven't encountered many of these guys personally, it would be the book I would strongly recommend.

Most of these are regional guides covering the fauna of areas ranging from whole continents to single small Counties or nature reserves. These books usually cover all Odonata, or one of the two suborders, or a family as in the German book series ‘Die Libellen Europas’. For more than a hundred years there has been a tradition of publishing lavishly illustrated and focussed books on charismatic butterfly groups: Ornithoptera, Troides, Morpho, Parnassius, Delias and Adelpha, to name but a few. By contrast there has never been a specialized book on a single conspicuous, tropical dragonfly group. Now we are pleased to introduce a pioneer product in this field: “The Metalwing Demoiselles (Neurobasis and Matronoides) of the Eastern Tropics: Their identification and biology” written by us and published by Natural History Publications (Borneo) in 2007. The book deals with all aspects of the systematics and biology of two calopterygid damselfly genera, Neurobasis and Matronoides, inhabitants of the Oriental region, Wallacea and New Guinea. Many odonatologists, who have seen these colourful winged insects in field, rank them among the most beautiful of all odonates. A brochure of the book showing 8 sample plates (in reduced resolution) is available at http://korento.net/metalwing_demoiselles.html As authors we refrain from passing judgement on the merits of the book, but so far we have received only very positive and enthusiastic comments of those colleagues who have seen it. If we wish to see similar specialized books on other tropical odonate groups being published in future, publishers must become convinced that there is a market for them. This applies equally to their willingness to publish cheap popular guidebooks, so needed to advance knowledge of tropical Odonata and promote their conservation, as the success of flagship volumes such as this one tends to have positive knock-on effects. In this only you, the potential buyers can help. We note in passing that we as authors receive no royalties for any sales, nor have received any payment for our efforts. The quickest and cheapest ($ 76 + $ 20 for shipping with DHL Express to US) way to get the Metalwing book is to order it from the publisher at http://www.nhpborneo.com/main.htm Other, much more expensive, options to purchase the book are also available on the internet.

If digital submissions are not possible, contact the Editor before sending anything. All material must be sent directly to the Editor, John C. Abbott . All articles and notes are preferably submitted in Word or Rich Text Format, without any figures or tables, or their captions, embedded. Only minimal formatting to facilitate review is needed—single column with paragraph returns and bold/italic type where necessary. Include captions for all figures and tables in a separate document. Include a title, author name(s), and contact information (especially email) with a line between each. The article or note should follow this information. Paragraphs should be separated by a line and the first line should not be indented. Where possible always refer to the scientific name of a species followed by its official common name in parentheses. Submit figures individually as separate files, named so that each can be easily identified and matched with its caption. Requirements vary depending on the type of graphic. Photographs and other complex (continuous tone) raster graphics should be submitted as TIFF (preferred) or JPEG files with a minimum of 300 ppi at the intended print size. If unsure about the final print size, keep in mind that over-sized graphics can be scaled down without loss of quality, but they cannot be scaled up without loss of quality. The printable area of a page of Argia or BAO is 6.5 × 9.0 inches, so no graphics will exceed these dimensions. Do not add any graphic features such as text, arrows, circles, etc. to photographs. If these are necessary, include a note to the Editor with the figure’s caption, describing what is needed. The editorial staff will crop, scale, sample, and enhance photographs as deemed necessary and will add graphics requested by the author. Charts, graphs, diagrams, and other vector graphics (e.g. computer-drawn maps) are best submitted in Illustrator format or EPS. If this is not possible, then submit as raster graphics (PNG or TIFF) with a minimum of 600 ppi at the intended print size. You may be asked to provide the raw data for charts and graphs if submitted graphics are deemed to be unsatisfactory. When charts and graphs are generated in Excel, please submit the Excel document with each chart or graph on a separate sheet and each sheet named appropriately (e.g. “Fig. 1”, “Fig. 2”, etc.) Tables may be submitted as Word documents or Excel spreadsheets. If Excel is used, place each table on a separate sheet and name each sheet appropriately (e.g. “Table 1”, “Table 2”, etc.) _______________________________________________ Odonata-l mailing list Odonata-l AT listhost.ups.edu https://mailweb.ups.edu/mailman/listinfo/odonata-l Subject: Re: Request for ARGIA Contributions From: "John C.

You can send content to me anytime, but I would like your submissions by no later than Feb. 25th to be considered for this issue. If you are not familiar with ARGIA, it is the News Journal for the Dragonfly Society of the Americas.

If digital submissions are not possible, contact the Editor before sending anything. All material must be sent directly to the Editor, John C. Abbott . All articles and notes are preferably submitted in Word or Rich Text Format, without any figures or tables, or their captions, embedded. Only minimal formatting to facilitate review is needed-single column with paragraph returns and bold/italic type where necessary. Include captions for all figures and tables in a separate document. Include a title, author name(s), and contact information (especially email) with a line between each. The article or note should follow this information. Paragraphs should be separated by a line and the first line should not be indented. Where possible always refer to the scientific name of a species followed by its official common name in parentheses. Submit figures individually as separate files, named so that each can be easily identified and matched with its caption. Requirements vary depending on the type of graphic. Photographs and other complex (continuous tone) raster graphics should be submitted as TIFF (preferred) or JPEG files with a minimum of 300 ppi at the intended print size. If unsure about the final print size, keep in mind that over-sized graphics can be scaled down without loss of quality, but they cannot be scaled up without loss of quality. The printable area of a page of Argia or BAO is 6.5 × 9.0 inches, so no graphics will exceed these dimensions. Do not add any graphic features such as text, arrows, circles, etc. to photographs. If these are necessary, include a note to the Editor with the figure's caption, describing what is needed. The editorial staff will crop, scale, sample, and enhance photographs as deemed necessary and will add graphics requested by the author. Charts, graphs, diagrams, and other vector graphics (e.g. computer-drawn maps) are best submitted in Illustrator format or EPS. If this is not possible, then submit as raster graphics (PNG or TIFF) with a minimum of 600 ppi at the intended print size.
