Fruit fly ovipositor. Coloured scanning electron micrograph (SEM) of the end of a fruit fly's abdomen, showing its ovipositor, the organ used by a female fly to lay eggs. This specimen is a Drosophila suzukii fruit fly, 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. Magnification: x165 when printed at 10 centimetres across.
