Wooing Fruit Flies

Wooing Fruit Flies

It’s common practice for animals to woo their partners through song – like us making a playlist of love songs. The male fruit fly is no exception – by vibrating his wings, he makes a type of song that attracts females and also signals other males to start competing for a mate. But how do the other files understand this? Scientists have identified a type of cell in male fly brains (in green) that provides a crucial link between their antennae, which detect sound vibrations, and an area in the brain that integrates courtship sounds with other mating signs like pheromones. Based on these cues, the brain realises it’s time to begin courtship and thus competition for a mate begins. While it may seem strange to care about the courting rituals of fruit flies, these experiments show us how our primal behaviours are ultimately dictated by what we hear, see and feel.

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
