This photo of a Harpobittacus tillyardi was taken at Mulligans Flat Woodlands Sanctuary near Canberra, ACT. This Hanging-fly has just grabbed its prey with its prehensile foot. Hanging-flies can’t walk with these opposing prehensile subsegments on their hind legs. They suck out the insides of their prey after injecting it with saliva leaving the exoskeleton after they have finished.
