This week brings us a fly from Ghana in the family Diopsidae, also called stalk-eyed flies. Why do would these flies have such long eye stalks? To impress female flies of course!
These flies feed primarily on bacteria, fungi and decaying organic matter. A less dramatic species in this family (Sphyracephala brevicornis)is found in North America and can be collected in the Northeastern United States as late as Thanksgiving.
