Primarily European earwig (Forficula auricularia)
Pest description and damage This introduced, nocturnal insect can devastate seedlings, flowers, leaves, and fruit. Adults are brown in color and roughly 0.5 inch in length. Easily recognized by the hind pinchers, called cerci, they are reviled by gardeners. The adults are winged, but the hind wings are folded under the short and stubby forewings. Immature earwigs resemble adults but are smaller, lack wings, and may be paler in color. However, earwigs also can be beneficial by feeding on aphids and other small insects. They also scavenge dead bugs and plant debris, or feed on live plant tissue. Earwigs chew irregular, variable-sized holes in leaves. Earwigs are often worse in dry eastern climates or in dry years.
