An image of mine (below) won the Image Laurel at the 2016 Horticultural Media Association Australia last night. You can read more about this insect here.

Image Laurel

The citation from the judges was: “Denis Crawford’s Mantis-fly image has superb resolution of detail revealing a technical mastery of close-up nature photography. The result is a crystal clear depiction of the Mantis-fly that brings the insect to life.”

Below is a short video of my acceptance speech:

I love parasitoids

To most people the word “parasite” conjures up all sorts of images from tapeworms to brain-eating amoebas to scenes from the film Alien. So a “parasitic wasp” must be something really freaky and horrible then? To us – no; but to an aphid or a caterpillar or some other target insect – yes.

Technically a parasitic wasp isn’t a parasite at all. True parasites like tapeworms don’t normally kill their hosts, because that would mean their own death. So insects such as parasitic wasps and flies which parasitise and kill other insects are known as parasitoids.

Mantispids, mantis-flies and misnomers

You can be lucky sometimes! I had read about the insects commonly called “mantis-flies” and seen many images of them, but I had never seen a live one in the flesh. We were at dinner with neighbours one night when one landed by my plate of food – no kidding. Pandemonium ensued as I tried to catch it, shouting for a container of some kind. Finally it was corralled and I had one to photograph. Here it is! (below)

Tomato fly

I picked a tomato off the bush the other day and noticed a little hole in it. I cut it open and saw that the contents were looking a bit ordinary, as if it was about to rot. Under higher magnification I could see the culprits – fly larvae – yep, maggots! The image below shows a close-up of one.

Fear and loathing

It happened one day at primary school back in the 1960’s. “It’s biting me, it’s biting me!!” the boy screamed as he sprinted past me. He then collapsed on the ground in flamboyant B-grade movie style, shrieking loudly. I ran up to him and could see the culprit clinging to his leg, a very large but harmless moth which I now know it to be one of the ‘rain moths’ of the family Hepialidae (below).

Gall-inducing insects

Have you ever noticed strange lumps and bumps on the leaves and stems of native plants? Galls are especially common on gum trees and wattles, and they are abnormal plant growths that form in response to invasion of plant tissue by a variety of organisms. Galls can be caused by certain species of wasps, flies, beetles, psyllids, coccids, thrips, moths and aphids, as well as by nematodes, mites, bacteria or fungi. This post concentrates on some common gall-inducing insects found in Australia. Continue reading Gall-inducing insects
