The eyes have it!

Posted by Bron (Canberra, Australia) on 25 May 2012 in Animal & Insect and Portfolio.

Robber flies are wonderful hunting flies whose eyesight ensures they eat (they don't know how to build supermarkets yet) Instead it's other flies and spiders on the menu.

About those eyes: They are compound eyes. Instead of one lens they see through two spheres with many lenses. Each lens of the compound eye sees its own image, so what the fly sees is like a mosaic. The more lenses, the higher the resolution. The two large spherical eyes of a fly provide an almost complete 360 degree vision.
