THE INSECTLIBRARY FIELD GUIDES

EarwigIdentification, facts & practical guidance

Earwigs are insects in Dermaptera, easily recognized by the pair of forceps at the end of the abdomen.

Compiled by the InsectLibrary Team · Updated · Editorial policy

Identification and lookalikes

The forceps vary with species, sex and age. Young earwigs resemble smaller adults but lack mature wings. The rear forceps distinguish them from many rove beetles with exposed abdominal segments.

Helpful predator or plant pest?

Earwigs can eat small insects and also damage tender plants or soft fruit. They shelter in cool, moist places during the day. Their presence alone does not establish the cause of leaf damage.

What to do next

Check damaged plants at night and reduce excessive hiding places near vulnerable seedlings. Indoors, remove occasional visitors and address entry gaps or moisture. Routine indoor pesticide use does not prevent new arrivals.
