I have reported on Tiger Beetles before on this blog. One sunny morning, I found this typically bark-running species sitting on a leaf in the sun. That presented an unusual photo opportunity.
The mandibles are for capturing and holding small prey.
There are at least two species in this genus in Australia. D. flavipes normally perches head downwards on rainforest trees where it captures unsuspecting passing insects. These beetles are frequently attracted to lights suggesting they may be at least partially nocturnal.
