Dragonflies and Damselflies - Order Odonata
This page contains pictures and information about Dragonflies and Damselflies that we found in the Brisbane area, Queensland, Australia.
To have a quick look on those beautiful animals, you can go to our Damsel Photo Gallery and Dragon Photo Gallery pages. For more details please proceed from below.
- Suborder are further divided into families. The families and genera classification of adult Odonata is mainly base on the features of wings venation, within genera is base on colour and genital feature. Followings listed the Odonata species that we can take their pictures so far. The dragonfly and damselfly species in Brisbane are much more than listed in this web site, however, to take their pictures is not easy. We hope we can build up the list with time. Please come back to this web site from time to time.
The insect Order Odonata includes damselflies (suborder Zygoptera) and dragonflies (suborder Anisoptera). Most of them are medium to large size, body length from 15mm to 120mm. Their bodies are long and slender, usually with a bright metallic colour. All of them have two pairs of membranous wings. Their hind wings and forewings are more or less similar size and shape. When they are at rest, the dragonflies held out theirs wings horizontally while damselflies held their wings vertically. They have very small antennae but very large compound eyes. They have the small three eyes (ocelli) as well. Their mouths are very good at biting (they don't bite or sting human). Their eyes and mouth occupy almost all their head. More about Dragonflies and Damselflies can be found on this page.
Dragonflies and Damselflies lay their eggs in flash water where the larva grow. Larvae need fairly precise habitat and sensitive to water pollution. Dragonfly adult is a predator in the sky and preying on flying insects. Larva may spend one to three years in water, depend on species, while adults live only a few weeks.
Damselflies - suborder Zygoptera
- Damselflies are usually smaller than Dragonflies and with slender body. They spend more time to rest and not flying in air than the dragonflies. When they are at rest, damselflies fold up and hold their wings vertically. Please visit the following pages and see what we found about damselfly.
Superfamily COENAGRIONOIDEA
-
Family COENAGRIONIDAE -
Pond Damselflies
- Coenagrionidae is the most abundant damselfly in Brisbane area. They are usually with black pattern, the ground colour may be green, blue, yellow, orange, or purple. Some species are two female colour forms, one of which is similar to the male. Their wings are usually colourless and clear. They prefer to lay eggs in pond or slow running water. Usually they are small and slender.
Family PROTONEURIDAE - Threadtail Damselflies
- The Threadtail Damselflies are small in size, their abdomen are pin-thin. Their wings are usually clean. We found only one species in Brisbane area. However, they can easily be found near semi-shaded running water. They usually rest in group on the plants at the water edges. They can still be be seen even in winter time. In summer, large number of them can easily be found.
-
Family LESTIDAE -
Reedings - The damselfly in this family has narrow wings and slender body, rests with wings closed. We found only one species of this family in Brisbane. We found them in early summer on the hill top of White Hill in Brisbane where was quite far away from any water. The female damselfly was camouflaged as part of the tip of the stem.
-
Family MEGAPODAGRIONIDAE
- Flatwings
- The Megapodagrionidae, or the Flatwings, is another damselflies family which can easily be found in Brisbane area. As their common name implies, when at rest, they spread their wings flat. They are usually metallic in colour, either green, blue or bronze. Females oviposit in tandem with males above the surface of the water and eggs are usually placed in plants.
Family DIPHLEBIIDAE - Azure Damselflies
- The Azure Damselflies are all in bright blue colour. This Damselfly family found only in Australia and New Guinea. They are large, thick body and rest with wings spread. Their wings usually have the large dark brown pattern. We found only one species in Brisbane area, the Rockmaster Damselflies, are large, thick body and rest with wings spread so you may think that they are the dragonflies.
Superfamily LESTOIDEA
Dragonflies - suborder Anisoptera
- Dragonflies are strong flyer and spend most of the time in air. Not like damselflies, you can hardly come close to them. They will fly away long before you come into the two meters distance. To take the pictures of dragonflies we need good camera, patient and luck. Following pages are the records on what we found about dragonfly.
Family AESHNIDAE - Hawkers
Members in this family are usually large in size. They are either blue, green, brown or yellow in colour with black markings. Their wings are always clear. They are commonly known as Hawk Dragonflies. They are strong fliers and may be found long distance from water. They spend most of the time flying and hunting for prey, seldom rest. When rest, they are usually in a vertical position.-
Family GOMPHIDAE - Clubtails - The Clubtails Dragonflies live in streams particularly in open forest. They are medium to large in size. They can be easily recognized by their smaller and widely separated eyes. They are green or yellow in colour with black strips. They have enlarge area in the end of abdomen and this is why they are commonly called Clubtails. The larvae burrow in the bottom sediments of the streams or wave washed shores.
-
Family PETALURIDAE
- Petaltails - The Petaltail Dragonflies are considered to be the most primitive dragonflies. All Petaltails are very large in size. They have separated eyes like the Clubtails family. Most of them are black or dark brown in colour. The pterostigmas on their wings are very long. Their males have the anal appendages enlarged like the petal, and this is why they are called.
-
Family SYNTHEMISTIDAE -
Tigerlet - The members in this family are commonly called Tigerlet. They are also known as Southern Emeralds. Most of them are small in size and with narrow abdomens. We found only one species in Brisbane. The dragonfly is metallic black with yellow in colour. Wings are clear with light brown colour. They can easily be found near Moolabin Creek and Oxley Creek in Brisbane.
-
Family CORDULIIDAE -
Emerald - Members in this family can be small to large in size, which generally have metallic green, black or yellow body. They have emerald eyes when matured, but often brown in immature stage. When perched, they usually hang suspended vertically. They are strong flyer and spend most of the time in air. We sometimes find them resting in our backyard where is at lease one km away from creeks or ponds.
Superfamily AESHNOIDEA
Superfamily LIBELLULOIDEA
-
Family LIBELLULIDAE - Skimmers - The dragonflies in this family are with distinctly broadened abdomen. They are from small to large in size. Their bodies is distinctively shorter than their wings span. They are usually red, yellow and blue in colour. Some species have wings patterns. They spend more time at rest than the dragonflies in other family. The males are territorial and will often return to the same or a nearby spot.
