Forficula auricularia (European Earwig)

Order: Dermaptera
Family: Forficulidae
Genus: Forficula

This is a European earwig, Forficula auricularia, which is one of the more common species. This species was introduced from Europe in 1912, and has since become widely dispersed throughout North America. Some earwigs are predatory, but most feed on living, dead or decaying vegetation. (1,2)  F. auricularia can become a plant pest when prey is scarce, causing damage to crops, fruit trees, and garden flowers. In Portland, Oregon in 1924, they became such a devastating problem that a state of emergency was declared and the city established a Bureau of Earwig Control. Normally, though, they pose only a minor threat. (1-4)
