Dragonflies and Damselflies

---

Percher, tiger-tail, skimmer, darter, duskhawker, longlegs, billabongfly, rockmaster, bluestreak, elf, forest-watcher, arrow, flutterer, prince, streamcruiser…. these are just some of the evocative names given to different species of Australian dragonflies and damselflies. 

There isn’t another group of animals that has such a colourful and energetic naming convention. But it seems appropriate because dragonflies are so captivating with their colour, speed, and radical manoeuvrability. 

They’re often moving so fast that all you get is a blurry colourful impression that stops momentarily to tease your eye-brain coordination before zapping off to chase down an unfortunate gnat or competitor who has encroached on their territory.

Dragonflies tend to be larger than damselflies and have their two sets of wings permanently held out perpendicular to their bodies. Damselflies are usually more petite and when they land their wings are folded along their bodies.

All of them are hunters - both as adults, which we see flying about, or as larvae that live in fresh water (in fact, for much longer than the adults fly about). 

It's this aquatic phase that keeps dragonflies tied to water bodies like Perry Lakes, though the adults can be found many kilometres away, and you’ve no doubt seen them in your own gardens helping to keep the mosquitoes and flies down.

Olly Berry (FoPL member and professional ecologist) has reported seeing four dragonfly and five damselfly species at Perry Lakes. Each species is distinguishable not only by appearance but also by occupying a distinctive niche in the prey it seeks and the way it hunts. Dragonflies and damselflies are most obvious in the warmer months when the adults emerge. 

The dragonfly and damselfly species observed by Olly Berry around Perry Lakes are listed below, but there are almost certainly more. FoPL members might like to keep an eye out for them. 

If you do see one, and are up for a challenge, try taking a photo. It requires a lot of patience, but the reward is to see the intricate engineering and beauty of these remarkable inhabitants of Perry Lakes. Also, you can upload your photos to the iNaturalist app. The image identification function is very good, and if it can't work what species it is, a very active group of experts is usually quick to provide an ID for you. It won't take you long to know our local species yourself. 

If you take a good quality photo of a dragonfly or damselfly and think it might be of value for our website, please send to wildlife@friendsofperrylakes.org
