Earwigs
Physical Features
Earwigs are typical insects with three body parts, six legs and antennae. They can be winged or wingless and are 1/4 to 1/2 inch long. Their narrow, elongated bodies are brown to reddish brown. Some species squirt an odorous liquid for defense, which can be smelled if squished by humans. Cerci extending from the abdomen are forcep-like. This feature often intimidates people fearing they will be pinched, but in reality the pinchers are unable to penetrate skin. The pinchers are larger and more curved in the males, they are used for a defensive and offensive weapon, and can be used to capture prey.
Life Cycle
Gradual metamorphosis
This process from egg to adult begins when females lay 20 to 60 eggs in burrows. The time taken for eggs to hatch depends on environmental conditions, but typically is between 20 to 70 days hatching when temperatures are cooler. The female exhibits maternal characteristics until immature forms (nymphs) leave the burrow after one season. Females “lick” individual eggs possibly to prevent fungi growth, guard eggs and nymphs, and feed nymphs until first molt.
