Fruit fly foot. Coloured scanning electron micrograph (SEM) of the foot of a male fruit fly (Drosophila melanogaster). The two claws are used to grip rough surfaces. The hairy adhesive pads, or pulvilli (beneath the claws), allow the fly to cling to smooth surfaces. Fruit flies are widely used in genetic experiments, particularly in mutation experiments, because they reproduce rapidly and their genetic systems are well understood.
