Hummingbird hawkmoths show eye and proboscis dominance while feeding, study finds
Hummingbird hawkmoths display a consistent preference for using one eye and one side of their feeding tube when extracting nectar from flowers. Researchers found this lateralization is instinctive, appearing even during the insects' very first encounters with flowers. By coordinating a dominant eye with a favored proboscis side, the moths are able to streamline complex feeding maneuvers. This behavioral trait is thought to conserve cognitive resources, improving efficiency during intricate tasks. The finding highlights a remarkable adaptation that allows problem-solving despite the insects having a very small brain.
