I was photographing bees on a tree heliotrope in Kawaihae when I saw this fly. It’s a new one for me, so I was happy to get decent photos and to be able to identify it afterwards.
This is a Feather-legged Fly (Trichopoda pennipes). It’s one of those flies which lays its eggs on host bugs, such as leaf-footed bugs and stink bugs. On hatching, the larvae make for the bug’s interior and develop safely within. The end product is a new fly and a dead bug. Because some of the bugs it uses as hosts are crop pests, it’s considered a beneficial insect.
The bottom photo shows why it got its name!
