Earwig, European

The European earwig (Forficula auricularia) was first observed in North America at Seattle, Washington in 1907. It spread quickly, and was reported from Oregon in 1909, British Columbia in 1919, and California in 1923. It reached Rhode Island in 1911, New York in 1912, and most other provinces and northern states in the 1930s and 1940s. Presently it occurs south to North Carolina, Arizona and southern California, but due to its preference for temperate climates it is unlikely to become abundant in the southeastern states. Also, it is not very tolerant of arid environments, but survives where irrigation is practiced. However, it is often intercepted in Florida and other southeastern states, arriving in shipments of produce and other products, as well as hitchhiking on motor homes and other vehicles (Paul Choate, personal communication).
