Fun Australian Insect Facts

All insects have three body segments; the head, thorax and abdomen.

All insects have three pairs of legs.

Insects are the only invertebrates with wings.

There are thought to be approximately 220,000 different species of insects in Australia (CSIRO, 2005).

There are currently around 86,000 species identified in 661 families. Going on these figures, there is a very good chance some insects you see have not yet been officially identified (Wettropics, 2006).

Worldwide, it is estimated that there are 30 million different species of insects, making up to almost 90% of all living things on the planet (Wettropics, 2006).

In Australia, it is estimated that insects make up almost 70% of the biodiversity (CSIRO, 2005).

"No one can live in or visit Australia without having personal contact with Ants" (CSIRO, 2005).

Australia has more than: 50 species of stick and leaf insects 162 species of mantis 250 species of cicadas 348 species of termites 428 species of cockroaches 550 species of shieldbugs 2,827 species of crickets and grasshoppers 4,000 species of ants 7,786 species of flies 20,816 species of butterflies and moths and 28,200 species of beetles! (Wettropics, 2006)

Field crickets (Teleogryllus commodus) die young due to the amount of chirping calls they make in an attempt to attract potential mates (Hunt et al, 2004)

When Female mosquitos (Anopheles gambiae) bite us, they like to add "insult to injury" and "urinate on us while they greedily gorge on our blood" (van Bergen, 2005)
