Extractions: We have quite a few different dragonflies and damselflies at Quoditch, not all of whom have, as yet, allowed us to photograph them. Here are some that we have seen. DRAGONFLIES This is a Yellow Ringed Dragonfly (Cordulegaster Boltoni). This is found at Quoditch from June to August. It has a wingspan of up to 105mm and a length of 125mm. You can't miss it when it flies past! It lays its eggs in the beds of fast-flowing streams. We found this one in field one about half a mile from the stream. Here is a female Common Darter Sympetrum striolatum) which we found in September 2003. Hover your mouse over the picture.The top view shows good use of disguise. We managed to get another couple of shots of the Common Darter in August 2004. These show a bit more detail. This lady was very co-operative and sat for ages, occasionally moving away and then returning to the same spot. picture to follow (we hope) We have also seen Emperor Dragonflies (Anax Imperitor). They are blue in colour and have a wingspan of up to 110 mm.. So far we haven't found one at rest to snap. Also in October 2001 a Southern Hawker was too busy flying around field three to stop and pose and again in August 2004 a male Southern buzzed around us trying to drive us off, but did not settle..

Dragonflies And Damselflies An illustrated essay with particular reference to the Bitter Lake National Wildlife Refuge, USA. http://www.microscopy-uk.org.uk/mag/artoct03/drdragon.html
Extractions: Gordon Warrick at one of the larger sinkholes, Bitter Lake National Wildlife Refuge. The sinkhole that stretched in front of Gordon Warrick and me was one of the larger ones. Nearby was Sago Spring, with its population of endangered spring snails and amphipods. These were tiny creatures, unlike the charismatic megafauna usually implied in the public mind when the word endangered is used. However the most exciting fauna to me were the odonates, which hovered and hawked in every direction. The largest were the darners of the family Aeshnidae ( Aeshna multicolor and Anax junius ). I also noted Libellula saturata , a bright orange-red skimmer (family Libellulidae). The males of this brilliant species are hard to miss as they patrol back and forth across the surface. At nearby sinkholes and adjacent grasslands I easily identified the males and females of the desert whitetail, Plathemis subornata , because of their banded wings and distinctive abdominal markings. Another interesting find was the seaside dragonlet ( Erythrodiplax berenice ), a dark small dragonfly that is usually found along Atlantic beaches! In the plants growing around the sinkhole numerous damselflies, members of the families Coeagrionidae and Lestidae, flitted lazily. The bluets (

Extractions: Editorial Current Editorial Letters to the Editor Ernie's Corner ... Guest Book THE DRAGONFLIES AND DAMSELSFLIES - by Bill Luscombe There are other insects that occur in trout waters besides the big four (mayflies, stoneflies, midges, and caddisflies). Dragonflies and damselflies make up a significant portion of a trout's diet during their season. Dragonflies, and their dainty relatives the damselflies, both belong to the order Odonata, dragonflies being the suborder Anisoptera and damselflies Zygoptera. Adult dragonflies are robust and are easily distinguished from the adult damselflies by their size, the fact that they are fast fliers, and that they hold their wings flat, at right angles to their body like an aeroplane when at rest. Damselflies are slim, slow fliers, and they fold their wings along their back when at rest. Adult damselflies also have the characteristic bright electric blue colouring with black bands along their abdomen.
Kansas School Naturalist: Checklist Of Kansas Damselflies A NOTE ON THE EVOLUTION OF dragonflies AND damselflies AND THEIR PLACE IN THE damselflies and dragonflies belong to a smaller group, the Palaeoptera, http://www.emporia.edu/ksn/v44n1-march1998/note.htm
Extractions: by Roy J. Beckemeyer and Donald G. Huggins A NOTE ON THE EVOLUTION OF DRAGONFLIES AND DAMSELFLIES AND THEIR PLACE IN THE INSECT WORLD Over ninety-nine percent of the insect species that have been described by scientists are placed in a group (Infraclass) called the Neoptera. These insects (including flies, bees, true bugs and beetles, for example) have the ability to fold their wings down flat against their abdomens. Damselflies and dragonflies belong to a smaller group, the Palaeoptera, which lack the added hinge which allows the Neoptera to fold their wings flat. The group Palaeoptera includes one other order of extant insects, the Ephermeroptera, or mayflies, and several orders of extinct insects known only from their fossils.

Global status of Dragonflies: Critical Species, Threats and Conservation in the International Journal of Odonatology . It will undoubtedly be of use to all nature conservationists, including odonatologists looking for global, but concentrated, information on the threats to dragonfly survival. Guardians of the Watershed has been compiled by 35 authors reporting on 22 regions and together they cover almost the whole world; only a few Asiatic regions remain uncovered. For each region a review on the odonatological history is given, critical odonate species, as well as critical habitats and sites are listed and general implications for necessary conservation measures and research are provided. Following on from the production of Guardians of the Watershed Other ongoing activities include the preparation of guidelines for "Important Sites Criteria" for Odonata which should be finalised by the end of 2005.

To assist the Sri Lanka Dragonfly Project, Jill Silsby (author of the Dragonflies of the World) has provided vernacular English names. Where there are names already in use, these have been used. For some species, she has coined suitable English names with reference to the text in de Fonseka and the Latin names ascribed to them. For some species no names have been coined as an examination of specimens or photographs will be required to coin a suitable English name.
Dragonflies And Damselflies A children s guide to British dragonflies and damselflies. http://www.cornwallwildlifetrust.org.uk/educate/kids/dragon.htm
Extractions: CORNWALL Most of Britain's original dragonflies and damselflies were exterminated by the cold of the last ice age after which re-colonisation occurred from Europe. Opportunist feeders, adult dragonflies and damselflies grab other smaller flying insects with their bristly legs. Damselflies and darter dragonflies wait on a perch, shooting off to seize a passing meal, whilst hawker dragonflies patrol an area looking for prey on the wing. Their ability for eating almost anything that flies and is not too big has stood them in good stead, and is reflected in the eating habits of the larvae. Detecting prey by sight, touch and vibrations, they devour everything from water fleas to each other. In turn, adult dragonflies and damselflies are eaten by birds such as flycatchers and wagtails, seized by frogs and toads, or trapped by spiders. Additionally, both they and their larvae fall prey to whirligig beetles and pond skaters or are dragged below by water boatmen and water scorpions. With up to 63 per cent of their total body weight made up of flight muscles, a streamlined shape and very large wings for their body mass, they are unmatched for speed and agility in the air. The jump jets of the animal kingdom, they can fly in any direction including backwards and sideways. Their wings are also used for signalling during courtship and territorial displays as well as absorbing heat like solar panels.

You instinctively know them when you see them, their long, narrow abdomens, richly veined wings and big bug-like eyes. "Dragonflies have many fan clubs, so few of them have earned spots on lists of endangered species," says David Liebman, a biologist and nature photographer in Norfolk, Va. Dragonflies and damselflies are members of the insect order called Odonata a Greek word that means "toothed one" for the toothed jaws of these predatory insects.

It holds its wings out to its sides when perched. Dragonflies also have very large eyes that touch each other in the center. Different species may be different colors: red, green, blue or brown. The adult Damselfly is similar, but holds its wings together over its back (like a butterfly) when perched. Its eyes do not meet in the middle of its head. Damselflies are also much smaller than Dragonflies. The Damselflies at Mather Field are usually blue or blue-green. Both Dragonfly and Damselfly larvae are aquatic. The

Place nymphs, especially the larger ones, alone in their own container or they will eat your other samples. Their gills are located at the tip of the abdomen. Dragonfly nymphs pump water out of a valve between the stiff epiprocts, and cerci. They can control this flow to shoot forward like a jet. Damselfy nymphs use their feather-like caudal gils as paddles, wiggling their body horizontally to swim. Both the dragonflies and damselflies found in this pond are climbers, and live generally amongst the submergent vegetation. They both hunt by ambushing their prey. They can extend their labium (Figure a.
