"Hawkmoths are able see in the dark, and now, researchers know how they do it. This ability allows them to track the movements of flowers blowing in the wind, even at night, as the insects hover in the air.
Manduca sexta, roughly the size of a hummingbird, were studied by researchers using infrared cameras as they traveled between mechanical flowers. As the team varied light conditions, they also altered the speed at which the artificial flowers swayed from side to side. They then recorded how well the proboscis (feeding probe) of the insects stayed within the target flower. The moths are able to slow down their brains while seeking nectar, improving their eyesight under conditions of low visibility, the study found. While their minds are working on reduced speed, the creatures are also able to maintain rapid flapping of their wings and maintaining complex flight characteristics."
