The head of a
flesh-fly, a family of
flies. Flies have a mobile head with eyes, and, in most cases, have large
compound eyes on the sides of the head, with five small
ocelli on the top. The
antennae take a variety of forms, but are often short, to reduce drag while flying. Fly
mouths do not contain teeth or anything else that would allow them to eat solid foods.
