Information on dragonflies and damselflies Learn all about dragonflies and damselflies! In the prehistoric jungles of some 300 million years ago, when trees were towering giants, dragonflies as big as hawks soared through the air! In the prehistoric jungles of some 300 million years ago, when trees were towering giants, dragonflies as big as hawks soared through the air. We know this because their prehistoric remains have been found in the Permian rocks of Kansas, in the Jurassic formations of Siberia and many other parts of the world. With wings nearly thirty inches from tip to tip, they were the largest insects that ever lived. Dragonflies were one of the earliest insect forms to appear on earth. The dragonfly has lived on as a creature from the distant past to this day, even while the dinosaurs passed into oblivion, and cavemen evolved into modern man. The only thing that changed about the dragonfly was its size. As the giant trees dwarfed, the dragonfly shrank. bodyOffer(23263) The dragonfly is very much a creature of the air and of the sun. Although it has legs, which are spine-bordered and bunched forward, so it can cling and climb, it never walks. But in the air, a dragonfly is as graceful as a ballet dancer, while it swoops, turns, and zooms about at will. It can dive like a small plane, or hover like a helicopter, as long as the sun is shining. Most dragonflies need the sun to fly, (except for a couple of Oriental species that hunt at night,) and will alight even when the sun goes behind a cloud for a few minutes. Dragonflies scoop up their victims with their legs, sucking their bodies dry and letting the carcasses fall to the ground. Dragonflies are beneficial insects, keeping the populations of pests like mosquitoes, down. Unfortunately, their nymphs are popular fish bait, so that in some parts of the country, they are in danger of becoming extinct!

63. Dragonflies And Damselflies Of Lincoln County, New Mexico An amazing list of dragonflies and damselflies found in Lincoln County, compiledby Robert Larsen, 1998. LINCOLN COUNTY ODONATA SURVEY By Robert Larson. http://www.rt66.com/~kjherman/odonata/4LincolnCo.html

LINCOLN COUNTY ODONATA SURVEY By Robert Larson The following list of dragonflies and damselflies for Lincoln County is the result of the first systematic survey of the Odonata for Lincoln County. Also, this is the first systematic survey of any county of New Mexico made in over 50 years. The dragonflies and damselflies have not been systematically studied in any geographical area of New Mexico since Harold B. Freshley's study of the upper Pecos in 1945. Those specimens collected this year were added to the checklist of New Mexico Odonata by Dr. Mary Alice Evans which was published by the Denver Museum of Natural History in 1995. The specimens were confirmed by Dr. John C. Abbott of the University of North Texas and the Lincoln County specimens are now in that collection. Hetaerina titia (Drury), an amethyst winged damselfly, is a new state record and was confirmed by Dr. Thomas W. Donnelly at the State University of New York and Director of the Dragonfly Society of the Americas. Lincoln, Chaves, and Eddy Counties are proving to be the most biologically diverse areas for dragonflies in New Mexico and eventually may show the greatest diversity of any area in North America. For example the British Isles show a total of 27 species of dragonflies, yet Chaves County has over 31 confirmed species. Newmans Lake and the Everglades, florida's most diverse areas, show only 21 localized species although, their state totals are very much higher than that of New Mexico. This is all ver interesting, of course.

Exotic Species Aquatic Invertebrates Dragonflies Damselfly nymph of the genus Enallagma . Notice the three long leaf-shaped gills at the hind end of its body. Class: Insecta - Insects Order: Odonata - Odonates (Dragonflies and damselflies) Family: Libellulidae - Common skimmers Characteristics of the family: Nymphs are crawlers that move about slowly in dense vegetation and bottom debris. They are usually long-legged and dull in colour. Interesting facts: Dragonfly nymph of the genus Erythemis Dragonflies are divided into two main groups: dragonflies (Anisoptera) and damselflies (Zygoptera). Adult damselflies usually rest with their wings folded upwards, whereas dragonflies hold their wings horizontally outwards. Damselfly nymphs have three external leaf-like gills at the end of the body, whereas dragonfly nymphs do not. Damselfly adults and nymphs are smaller and more slender than dragonfly adults and nymphs. Representative genus: Dragonflies of the genus Erythemis (described here in their nymph stage) Description Nymphs are short and broad with long legs. Unlike many in this family, animals in this genus lack dorsal hooks on the abdomen. Because they are such slow-moving, sedentary animals, they are often fouled, or coated with a layer of algae or sand that persists until the animal moults.

66. Dragonflies And Damselflies Of Fiji dragonflies and damselflies of Fiji. One of the As well as dragonflies,there were also quite a few damselflies at Koroyanitu. I ve seen http://www.richard-seaman.com/Insects/Fiji/Odonata/

Dragonflies and Damselflies of Fiji One of the first dragonflies I came across in Fiji remains one of my favourites. Around the world it's very common to come across green dragonflies, and quite common to come across red dragonflies, but it's not so common to find one which is red and green - in fact this is the first one that I can recall, and I only saw one of this species while I was in Fiji. This particular individual was quite a long way up a ridge on a logging track behind the Silktail Lodge at Devo on the Tunuloa Peninsula, which is also known as the Natewa or Cakaudrove Peninsula. Look closely and you'll notice that this dragonfly is only standing on four of its legs, and it has its other two legs tucked up behind its eyes. This is a piece of behavior also seen amongst quite a number of butterflies. Here's one of those common green dragonflies I told you about! It was on the same logging track as the previous individual, and you'll see that this one too has a pair of legs tucked behind its eyes! This type of dragonfly seemed to be more common than the red and green one - at least I encountered it in more places. Here's what I think is the same species, but this time beside the Narange creek up in the Korayanitu National Park, near Nadi on the main Fijian island of Viti Levu.

A list of species has been published previously (Pinhey 1984, 1985), and the distributions and periods of adult activity are taken from that source. The nomenclature of southern African Odonata is currently under review (see below). Changes to the names (presented here) may well occur during the latter half of 2000.

These dragonflies are confined to the southern half of Britain where they may be observed almost ceaselessly patrolling. They are fiendishly difficult to approach for photography and the best opportunities are often presented by ovipositing females (as shown). The flight period is later than that of the similar Norfolk Hawker (see Dragonflies and Damselflies 3 and ) with little or no overlap in July.

On hot June days these dragonflies are most easily seen patrolling well above head height. The early flight period does not normally overlap with that of the Brown Hawker , the only possible confusion species (see Dragonflies and Damselflies 1 for comparison). The green eyes and the yellow triangle on the second abdominal segment are absent in this latter insect. The illustrated dragonfly flew right in front of the photographer as he was returning home after a long, hot and fruitless search and settled in a tree right beside the path, allowing a mixture of still and mini-DV images (captured still shown) to be taken. The conditions for photography were far from ideal with fierce natural backlighting making accurate exposure difficult. Another illustration may be seen on Dragonflies and Damselflies 5 The

GardenLine Porpourri - Miscellaneous Bonnie Willie In the last few weeks it may appear that mosquitoes have taken over Saskatchewan. A stroll in the park can no longer be considered enjoyable. Children must wear long, baggy clothing in order to enjoy outdoor play, no matter what the temperature. But, as mosquito populations rise, the number of dragonflies also tend to increase. Some people consider dragonflies and its smaller relative the damselflies, to be ugly, bothersome pests, but upon closer inspection, one realizes the beauty contained within their fine wings, and soon begins to appreciate their aggressive role in natural mosquito control. Description: Damselflies and dragonflies are members of the insect order Odonata. Both have chewing mouthparts, bristle-like antennae, very long slender bodies with 4 long and narrow wings. The wings are net-veined of equal size or slightly smaller. Both are similar in appearance, but the damselfly tends to be much smaller and more delicate in construction. The dragonfly's body tends to be wider with stiffer wings. The only other real difference between the two is the manner in which they hold their wings. Dragonflies hold their wings perpendicular (at a 900 angle) to their body when at rest, whereas the damselfly will hold their wings behind them, parallel with the rest of their body. Adults of both the damselfly and dragonfly are usually found near water. The nymphs or immatures live in the water. Both nymphs and adults are predators, devouring mosquitoes, midges and other small annoying insects. Adult dragonflies will try to bite if handled by humans and if the dragonfly is quite large, a painful pinch may result.
