Earwig


Nocturnal insect of the order Dermaptera. The forewings are short and leathery and serve to protect the hindwings, which are large and are folded like a fan when at rest. Earwigs seldom fly. They have a pincerlike appendage in the rear. The male is distinguished by curved pincers; those of the female are straight. Earwigs are regarded as pests because they feed on flowers and fruit, but they also eat other insects, dead or alive. Eggs are laid beneath the soil, and the female cares for the young even after they have hatched. The male dies before the eggs have hatched.

When threatened, earwigs spray quinones (irritant chemicals stored as crystals), from their abdominal glands.
