This page contains pictures and information about Dragonflies and Damselflies
that we found in the Brisbane area, Queensland, Australia.
To have a quick look or to identify those beautiful animals, you can go to our
Damsel
Field Guide and Dragon
Field Guide pages.
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.
Dragonflies and Damselflies lay 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.

- Dragonfly Head
-
- Dragonfly has a pair of large compound eyes which covered most of its
head. Watch carefully, we can also see its pair of small antenna and three
ocelli. Click here for a closer look to the dragonfly's thorax and head.

- Damselfly Wings
- The main veins and the crossveins form the wing venation pattern. The
venation patterns are different in different species. There may be very
numerous crossveins or rather few. The venation
pattern is useful for species identification. More information on this
page.
- Dragonflies and Damselflies Habitat
-
- Most of the Dragonflies and Damselflies listed in this web site are found along the
Bulimba Creek. Bulimba Creek is in the south-eastern areas of Brisbane and flows generally north into the Brisbane River. Along the creek there are the
bushland and freshwater swamp lands.
The creek flow across most of the southern suburbs in Brisbane, including
Sunny Bank, Eight Mile Plains, Wishart and Mansfield. Along the creek, there are the fast and slow running sections, there are
also still water ponds. Provides suitable habitats for dragonfly and damselfly larvae.

- Dragonflies Life Cycle
-
- Dragonflies adults are colourful but their larvae are
less familiar. The grow of dragonflies can hardly be classified in to
in-complete metamorphosis nor complete metamorphosis. Metamorphosis
in Dragonflies and Damselflies
is quite different form other insects. Their larva look different from
adults but they do not have pupa stage. Dragonflies and Damselflies lay
their eggs in flash water where the
larva grow. More information please click here.

- Mating and Reproduction
-
- Their reproduction and
associated behaviour is unique among the animal world. The behaviour is complex
but universal within dragonflies and damselflies, although with difference spices there could be some minor variations.
