Jewel beetle

Castiarina octomaculata


This orange jewel beetle is a mimic of a ladybird beetle. This common species is dependent on flowering tea tree and times its emergence with the short flowering season. They are most prolific on the warmest days. I have not observed mating behavior before and it provides a great confirmation of the dimorphism between sexes.

Thanks Mark.
This is the other common one that I expected to find today. Only one. There are several other species that we will find here this season.
We might need another few hot days.

Ah great find Martin. The male looks considerably smaller. No sign of the blue/orange one today I suppose?
