105. Biology Of Dragonflies And Damselflies The Biology of dragonflies and damselflies. Terminology In some uses, the term dragonflies includes damselflies too. Checklist of California Odonata. http://uci.net/~pondhawk/odonata/odonata.html

The Biology of Dragonflies and Damselflies Terminology: In some uses, the term "dragonflies" includes "damselflies" too. Checklist of California Odonata Dragonflies, robust insects ranging in body length from 1 to 4 inches are excellent flyers often executing rather intricate aerial maneuvers in the search for food and mates. In general they eat flies, mosquitoes, gnats and other flying insects. They do not bite. They do not attack people although it may seem that way if one decides to snatch an insect off your person. At rest the wings generally lie flat, at right angles to the body. Some species often rotate and extend their wings forward to help regulate their body temperature. In rare circumstances, young dragonflies may fold their wings over their backs. The insect you see flashing along the water's edge spent the early part of its life as a much different sort of creature in fresh water. Damselflies, related to dragonflies, are generally smaller and much less robust. They are weaker flyers, many preferring to move from plant to plant searching for food. They eat smaller prey some of which may be gleaned from the vegetation. At rest the wings do not lie flat but are folded up over their backs sometimes in a V shape. Life Cycle The eggs are laid in or near water, often attached to vegetation. In some cases, the eggs are just tossed into the water. The female may become totally or partially submerged during the egg-laying process. Temporary and permanent sources of water are used.

Environmental Interpretive Center The Odonata Order: Dragonflies and Damselflies Go to Key Both the nymphs and the adults of dragonflies and damselflies are excellent predators. 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.

108. Dragonflies And Damselflies Of Central Park To find dragonflies and damselflies, seek out the numerous bodies of water throughoutCentral Park. damselflies are usually smaller than dragonflies. http://homepage.mac.com/edlam/DD_CP.html

Male Ebony Jewelwing Turtle Pond is the best location in the Park for dragonflies and damselflies. In 1997, it was enlarged and re-landscaped with a wildlife blind and new plantings. As a result, 1998 was an exceptional year with the appearance of a number of species not seen before. Maintaining good water quality seems to be the most important factor in attracting odonates. Turtle Pond attracts odonates seeking to mate. The male, using claspers at the end of his abdomen, grabs the female by the head or just behind her eyes on the thorax. He then curls to transfer sperm from his abdomen tip to a secondary copulatory organ at the base of his abdomen near the thorax. The female completes the mating by curling her body so her abdomen tip contacts with his secondary organ. The resulting coupling often appears heart-shaped and is called the "wheel." Damselflies in wheel After mating, the pair may separate or, in some species, the male will continue to hold onto the female, guarding her from other males. Paired couples are described as being "in tandem." The female then lays her eggs, a process called ovipositing. In most cases the female dragonfly drops her eggs in flight, hovering and repeatedly dipping her abdomen into the water. Other dragonfly species, and most of the damselflies, lay eggs on or inside the stems of aquatic plants. Basic structure of adult damselfly.

110. Gordon's Odonata Page An introduction to the biology and ecology of Damselfliesand dragonflies, The Odonata. Dragonflies (Odonata). http://www.earthlife.net/insects/odonata.html

Dragon-flies (Odonata) Menu Introduction Ecology Taxonomy Eggs ... Bibliography Introduction Dragonflies are a well known and fascinating order of insects; you will likely see plenty of them as you go out into the field in late summer, normally near water. They are more common in warmer parts of the world than in temperate areas like the UK and of the 5 300 named species world-wide, only 38 live and breed in Britain. They are conveniently divided up into two groups Anisoptera the true Dragonflies which rest with their wings out from their body in a cross shape and Zygopteran or Damselflies who hold their wings above their body. In this article when I say Dragonflies I will mean both Anisoptera and Zygoptera, but I will use these terms separately when talking about the individual groups. Dragonflies have strongly biting mouthparts and are active and aggressive carnivores, both as adults and as young (called nymphs), preying mostly on other insects. The adults have massively large eyes, often meeting at the top of the head in Anisopterans. These eyes may each contain as many as 30 000 individual lenses or ommatidia (your eyes have only one lens each). Because of this Dragonflies have exceptionally good eyesight and have been known to respond to stimuli from more than 40 feet away. They have very small and poorly developed antennae though. They have two pairs of almost equally sized long thin membranous wings; both pairs of wings usually have a stigma (a dark or coloured patch near the middle of the leading edge) and a mass of cross veins giving them the appearance of being a mesh. Unlike most insects, which either flap both pairs of wings in unison (i.e. Bees and Butterflies), or only flap the hind pair (i.e. Beetles), or only have one pair (i.e. Flies), Dragonflies can flap or beat their wings independently. This means the front wings can be going down while the back ones are coming up. You can see this happening if you watch closely. Dragonflies are excellent fliers, particularly the Anisopterans and can loop-the-loop, hover and fly backwards quite easily. It is not unusual for the larger species to reach 30kph and the Australian

Widow Skimmer (male) Photo by Jim Mason Dragonflies and damselflies are insects in the Order ODONATA . They are some of the more noticeable insects, especially around the bodies of water that they call home. Their amazing aerial capabilities and superb sense of sight make them fascinating creatures to watch. As with birds, learning to tell the different species apart would seem to be an obvious first step into their world. But an easier step is to observe their different behaviors instead! A small pond may have 6 or more different species active at one time. The observant naturalist will notice that: A lot of their activity has to do with breeding. Being insects, this is no surprise, but their high visibility means this is all out in the open where it can be easily seen. Males joust with other males for territory and chase females. (Males confident of their status may just raise their tail in the air while perched to fend off rivals.) Mated pairs of some species fly around in tandem. The male flies in front, holding the female by the nape of her "neck" with special claspers on the end of his abdomen as the female lays her eggs. Males of some other species will guard the airspace around a female they have mated in an attempt to prevent other males from mating with her.
