Forficulidae (Earwigs)



Earwigs, in the order Dermaptera, include six families in the United States. All of the earwigs in Bee Atlas blocks are in the family Forficulidae, and are most likely the common European earwig.


Contrary to their common name, earwigs are no more likely to crawl in your ear than any other insect. They are commonly found in leaf litter, under bark, and in riparian areas. One of their more prominent features is a pair of pincers, or cerci, found at the end of their abdomens. Earwigs prey on other insects and arthropods and bits of organic matter.

Nest Structure

Adults lay their eggs in one location and tend to the eggs and nymphs until they can fend for themselves. They are probably using the nesting block tunnels as a sheltered overwintering place.
