intact ocellar retinas. A graphical representation
of the fields of view is shown in

their flight is significantly influenced by an aux-
iliary visual system known as the
ocelli.
The ocelli are simple eyes mounted on the
front of the insect's head. The fields of view of the
ocelli in the species
H. papuensis
