In Australia we see Tiger Beetles at the light sheet every night during the summer season and they can be spotted during the day where they actively pursue small insect prey. I have noted this before in this blog. I often see these beetles on tree trunks in the rainforest facing head downwards awaiting unsuspecting insect meals during the day. Recently at a site in a mixed eucalypt-acacia forest along the Clohesy River we found two species of the genus Dystipsidera. When spotted during the day on tree trunks, these beetles are alert and very difficult to approach. With their propensity to be attracted to lights, I had thought that they might be nocturnal. They are known for their extraordinary eyesight and could potentially see on bright, moonlit nights.
Two species were spotted sitting on leaves or grasses and they seemed to be active. But they were within 15m of the light sheet and that could have prompted their movements.
Always something of interest in this great country.
