Extractions: DRAGONFLIES AND DAMSELFLIES Extracts from a London Wildlife Trust publication by Gina Oliver 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.

Extractions: 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. 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.

Extractions: Peabody Park Survey Dragonflies and Damselflies This page is part of a biological survey of Peabody Park at the University of North Carolina at Greensboro. Initials of determiners and locations of grid sections are explained on the references page. There are perhaps a dozen species of dragonflies and damselflies in Peabody Park, but they have not been studied. This group would make an excellent research project for an interested biology student. The earliest adults can be found in the Park fields in the first week in April.

Dragonflies And Damselflies: Order Odonata
Here you will find some of the best and most useful websites about dragonfliesand damselflies, the beautiful and ferocious Odonata.
http://animals.about.com/cs/dragonflies/

Extractions: Guide picks Dragonflies and damselflies, members of the order Odonata, are some of the most ferocious predators of the insect world. They are also among the most primitive of the flying insects. They spend their childhood in the water being predaceous, and their adulthood in the air being predaceous. They are valuable consumers of large quantities of flies and other pests.

Extractions: These often brightly coloured, fast flying insects are well known and easily recognised. Dragonflies and damselflies are medium to large insects with body lengths ranging from 15-120 millimetres. They are often seen flying rapidly over streams and lakes, or through gardens at dusk, often following regular flight paths every day. Dragonflies and damselflies can be recognised by the following features: Damselflies and dragonflies are very similar but can be separated by looking at their wings. In dragonflies the hind wings are slightly broader than the forewings and in damselflies both wings are more or less similar size. Wings are held horizontally to the body in dragonflies and vertically in damselflies when at rest. Dragonfly Damselfly The nymphs of these insects are aquatic and bear only a slight similarity to the adults. They are wingless and have a broader more flattened body shape. Dragonflies have gills within their body while damselflies have 3 leaf-like gills protruding from the tip of the

Extractions: The Swamp Darner is our largest dragonfly. The best locations to observe dragonflies in the Ojibway area include the pond in front of the Nature Centre and the ponds at Tallgrass Prairie Heritage Park. The mouth of Turkey Creek at the Detroit River is a good location for stream species. Many odonates wander far from water and can be found in open areas and along trails. The following fifty-eight species are listed as (C) common to abundant, (U) uncommon, and (R) rare to single occurrence. Common names follow usage by the Dragonfly Society of the Americas .

Extractions: Dragonflies are larger than damsels, and dragons rest with wings outstretched, damsels with wings along the abdomen. Larvae are aquatic predators. Return to Insect Index Cambridge, garden, 8th July 2001. Photographed at Cambridge 9th September 2000. Not much bigger than a damsel fly - this one is about 43mm long overall. This is a female - males are rather reddish in colour. Female Ruddy Darters Sympetrum sanguineum are rather similar but have all black legs and are rather smaller (35mm). On this specimen the legs (inset) are at least partly light colour.
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

Extractions: 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.

Extractions: Zygoptera (Damselflies) habitat all freshwater wetlands including lakes, ponds, marshes, streams, rivers and vernal pools size 2.2 to 8.0 cm long (adults) description The adult Dragonfly has a long narrow body. 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

http://www.ru.ac.za/zoology/Martin/odonata.html

Extractions: Yours is the access since 1st January 2000 The damselflies and dragonflies of South Africa are currently classified into two suborders, containing seven and four families respectively. 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. Information about the Odonata and their phylogenetic position can be obtained from Suborder: ZYGOPTERA Superfamily: Calopterygoidea Calopterygidae Chlorocyphidae Cowley, 1937
