Pulvilli On A Fly's Foot, Sem
Photograph - Photograph
Fly's foot. Coloured scanning electron micrograph (SEM) of pulvilli (tubular hairs) on the base of the foot of a fly (order Diptera). Each pulvillus secretes a solution that forms a bond with the surface on which the fly is standing. This allows the fly to walk on vertical surfaces, or even upside down.
