Lots of these click beetles were flying around one particular tree (I’m sorry I didn’t identify the tree!). They are pretty big and their method of flying is quite ungainly, elytra out to the sides and abdomens hanging down, making them look like flying crucifixes. They were very active and wouldn’t keep still to be photographed but I managed to catch one in my hat. I put it on a leaf and it immediately took off again! By the way, the male uses its huge feathery antennae for detecting females.
