The family Diopsidae is probably one of the families of Diptera easiest to recognize. All species of these stalk-eyed flies carry their eyes and antennae at the end of lateral projections of the head. Eye stalks also occur in other families of Diptera, like Drosophilidae, Micropezidae, Tephritidae s.l. (incl. Otitidae and Platystomatidae), Periscelidiae and Richardiidae, but in these families only a few taxa are involved, while the stalks do not carry the antennae and are often limited to the male sex. In some species of the Tephritidae s.l. (Phytalmiidae) and Clusiidae lateral head projections occur, which carry neither eyes nor antennae.weiterlesen
