These type of flies are often very colourful and are easily recognized. Dragonflies and
Damselflies are middle to large in size and 15-120mm in body length. They can often
be seen flying across a lake or river, near organic places and are seen near gardens filled
with flowers at the dusk of the night. Dragonflies and Damselflies can be recognized and
known by the following features:

Abdomen is long and very slender
Large compound eyes
3 Ocelli
Very small antennae
Mandibulate mouth parts
Two pairs of membranous wings similar shape and size
Complex wing venation with many cells
Nannophya dalei
Dragonfly
Dragonflies and Damselflies are nearly identical if you have a look at it but are actually very
different from each other you can tell by looking at the wings here’s an example:
Dragonfly
Damselfly
You see how the Dragonfly (Left side of the screen) has laid out wings and fairly short ones
and as you see the Damselfly (Right side) has more stiff wings and more longer.
You can also tell by the abdomen see how the dragonfly has a short one and the damsel fly
has a long one?.
Mating usually takes place on the wing and the male dragonfly (or Damselfly) guards the
female as she fly's over the surface of the water depositing her eggs. The nymph (The
baby) spend mostly their whole life under water and then they moult nearly up to 15
times before they emerge into a full adult Dragonfly(or damselfly).
Dragonfly Nymph

When fully mature the final instar come and crawl onto overhanging rock(pebbles) or
vegetation(plants) where they go to shed they’re last nymphal skin and emerge as a
adult getting ready to hunt and mate.
Dragonflies and Damselflies are carnivores as both adults and nymphs. The nymphs usually
feed on invertebrates (An invertebrate is an animal without a vertebral column.) They
catch them with they’re specialized mouth parts that are able to reach and stretch to
seize and attack they’re prey. The Adult Dragonfly (or Damsel) hunts and sneaks and
attacks their prey, they also hunt flying insects by behind and puts they’re legs on
they’re prey to grab them.
Dragonflies and damselflies are found all over Australia though, they do need water to
mate, one by one (Individual) can be soon flying km to fresh water. The Male Dragonfly
(or Damselfly) seems to be very territorial of intruders because they usually settle near
places filled with other insects and usually water and they think that it could be a good
place to hide to attack intruders from invading they’re territory. They often perch from a
rock or bush Protruding (Sticking out/Out in the open) from the water and flying rapidly
across the river (They’re territory). They fly over they’re territory to check if intruders
are coming to attack .1 If they do attack the dragon fly (or damselfly) the dragonfly runs
after the enemy persistently .2 They keep guarding.
A dragonfly/damselfly eats smaller bugs, and gets eaten by frogs, other dragonflies, and
other, bigger creatures. The dragonfly is very important, just like every other
insect/animal in the food chain. To get more info and to understand it more go on my
actual wikipage.
This is my drawing of a dragon fly.
Sorry , I copy-pasted this one since they’re was so much. Some got me tongue twisted!

Did you know the Odonata lived 250 million years ago and they’re still here!?
250 million years ago they had a wing span of over 70 cm (1m & 10cm) imagine that!
Some of the large Odonata can fly 70 km/h basically the fastest flying insect on earth!
There are 6,000 species around the world!
The Dragonflies are stronger then the Damselflies but the Damselflies are faster.
The Adult Odonata usually hangs out near water.
There are 320 species (Estimated) in Australia
The Suburb in Australia with the most species is Sydney
People call the Odonatas Larvae’s eyes “Mud-Eyes”
