Field Notes

Description:

A small metallic coloured leaf beetle which looks like it's made of copper right down to the dent-like pits and even some small rivets. Approximately 8mm long.

Habitat:

On a wall in a local nature reserve dominated by small eucalyptus but with many indigenous understory species including acacia, gahnia and leptospermum.

Notes:

For some reason or other this one seemed much darker with flash on than without. Haven't worked that one out yet. <br>
Called 'Klamath Weed Beetle' overseas. <br>
Apparently this was deliberately introduced as a biological control agent to keep 'St John's Wort' (Hypericum perforatum) down and was regarded as successful. http://www.projectnoah.org/spottings/213106155 It is now 'naturalised.

Oh brilliant thanks Martin. Quite a pretty little character but different from our natives. Being a foreigner would explain it's slightly unusual appearance. A St John's wort agent eh. This will be an interesting read.
Nice beetle! Chrysomelidae, of course. Not sure if it is supposed to occur in Australia but I saw it too; http://www.projectnoah.org/spottings/237646071 and Nick has it on lifeunseen, where I got the ID from.
