Fruit fly (Drosophila suzukii) head. Coloured scanning electron micrograph (SEM) of the head of a fruit fly, showing its large compound eyes (red, centre left and right) and mouthparts (lower centre). This fruit fly is a pest of fruit crops and a serious economic threat to soft summer fruit. Females infest thin-skinned fruits before harvest and the larvae destroy the fruit pulp by feeding on them.
