FliesPollinators and Flies The Eyes of Flies

Species in the order Diptera, have compound eyes. These large eyes that can be seen on either side of the insect’s head, contain many small lenses (sometimes thousands).

The compound eyes may meet on the top of the head or may be separated. In many male fly species, the eyes are “holoptic”, meaning they meet in the middle (almost touch), whilst in the female they are separated (an obvious space between the eyes). This is one of the feaures that distinguish the sexes of flies in many species.

As well as the compound eyes that are easily visible in the adult insects, they also have three small ocelli, located in a triangular formation on the top of the insect’s head.

The compound eyes can be quite strikingly different between species, varying in colour and patterns.
