Coloured scanning electron micrograph (SEM) of Fruit fly tarsal claw and pulvilli (Drosophila melanogaster). Pulvilli are the hairy adhesive organs at the end of Dipteran (fly) legs (usually located at the base of the claws). Tenent setae are the hairs (with adhesive ends) that make up a puvillus. An adhesive substance is secreted through the tubular tenent setae allowing a fly to attach to smooth surfaces. Drosophila is a genus of fly from the family Drosophilidae. The species Drosophila melanogaster is known as the common fruit fly or vinegar fly. Drosophila melanogaster is widely used for biological research in studies of genetics, physiology, microbial pathogenesis, and evolution. This fly can be an agricultural or household pest. Magnification: x185 when shortest axis printed at 25 millimetres.
