This emerged from a fish tank that sits on my desk at work! I had planted it with millfoil from my pond at home and larvae or eggs came along for the ride.
The larvae in the shot (known as a mud-eye) is actually the hollow case that remains after the adult has emerged through a slit in it's back.
I caught the adult, which was fluttering at my ...

It also occurs in New Zealand. It's pupa feed on a number of species within the nettle family - Urticaceae - including both Australian natives and introduced species, such ...

I found this Katydid in my garden yesterday. Going by photos I can find on the web the species appears to be the Common Garden Katydid (Caedicia simplex). However given that there are over a thousand katydid species in Australia, I'm not 100% sure. (I've got a big collection of flora and fauna ID books, but don't yet possess the Guide to the Katydids of Australia.)

I have a pond in a ceramic bowl in my front garden, about a metre across, planted with aquatic plants. Damselflies are cruising around it. My best guess on the species is the Wandering Ringtail (Astrolestes leda) - assuming that this bloke knows what he is talking about. Damselflies differ from Dragonflies in that they rest with wings folded rather than to the side. Like dragonflies their larvae are carnivourous and aquatic.

I got this shot among the coastal dunes in Bongil Bongil National park just south of Coffs Harbour, NSW. It was during one of the rare periods of sunshine in the leadup to the east coast floods. There were dozens of butterflies and if I'd had another few minutes I would have got the perfect shot. My holiday got cut short and I came home with few photos. But I can't grumble ...

Having planted a diverse mix of native plants in my garden, all manner of native insects have moved in. This little native bee is feasting on pollen and nectare from my common everastings. You can see that it is covered in pollen, so is acting as an effective polinator.
There are about 1500 species of native bees in Australia. They are generally smaller than the introduced bee. Most are solitary, but there are ten species that are social. The solitary ones do not produce honey. The social ones produce honey and are stingless.

Trigger plants (Stylidium graminifolium in this case) are fertilised by native bees or wasps. The petal arrangement resembles the wings of an insect and the flowers possibly send out a scent that entices some insects to attempt to mate with them. When a bee or wasp tickles the centre of a flower, the tensioned anther column flicks over whacking the amorous visitor with a puff of pollen. When this is repeated with another flower, the unwitting Romeo cross-fertilises them.
