Abstract:Summary In a flight position with vertical body axis, both the lsquodorsolateralrsquo and the characteristic lsquoventralrsquo lens eyes of male coccid insects are arranged in a horizontal ring around the head. The interpretation that they mainly serve for stabilizing the flight position with regard to the horizon can explain the extraordinary structural features known for these eyes.
Keywords:Coccida  vision  ocelli  flight
