Animated coloured scanning electron micrograph (SEM) of Mediterranean fruit fly pulvillar pad with tenent setae (Ceratitis capitata). Pulvilli are the hairy adhesive organs at the end of fly legs. Tenent setae are the hairs (with adhesive ends) that make up the puvilli. The pulvilli allow the fly to attach to smooth surfaces. Ceratitis capitata, called the Mediterranean fruit fly, is from the family Tephritidae. This fruit fly is the world's most destructive fruit pest. It is native to the Mediterranean regions, but has spread invasively to many parts of the world. Although it may be a major pest of citrus, it is often a more serious pest of some deciduous fruits, such as peach, pear, and apple. The larvae feed upon the pulp of host fruits, sometimes tunnelling through it and eventually reducing the fruit to a juicy, inedible mass.
