The scorpion fly (Panorpa communis) is named for its curved 'tail' that looks like a sting. It is, in fact, the males' claspers for mating. The tail is not seen in the female. Yellow and black, with a long 'beak', it scavenges on dead insects and frequently steals the contents of spiders' webs. There are around 600 species worldwide.
