Do look down

Whilst not insect navigation per se I was interested in this article because it highlights how sensory systems can be adapted to the environment and task at hand. Flying insects use optic flow field to correct for unintended rotations and translations. The flow fields that are consequent on translation are driven by the apparent movement of nearby objects which in natural conditions are usually beneath the animal. Here Mazo and Theobald show that flies will ignore (i.e. make no corrective movement in response to) translatory fields that are presented above them. Thus demonstrating that the fly sensory system is tuned to the natural distribution of objects.

Mazo, C., & Theobald, J. C. (2014). To keep on track during flight, fruitflies discount the skyward view. Biology letters10(2), 20131103.
