Common Earwig

(Forficula auricularia)

Despite popular belief, and its name (from the Old English for 'ear beetle'), the Common Earwig will not crawl into your ear while you sleep – it much prefers a nice log or stone pile! It feeds on organic matter, recycling important nutrients.

Overview

The Common Earwig is nocturnal, scavenging on dead plant and animal matter at night and retreating to hide under stones or in rotten logs during the daytime.

Female Common Earwigs are excellent mothers: laying their eggs in damp crevices, they guard the nest and gently clean the eggs until the young hatch. They will then guard the young until they are ready to fend for themselves. The pincers of the common Earwig can give a human a small nip, but they are generally used to scare off predators.
