Common Earwig

Nocturnal omnivore with distinctive forceps-shaped cerci. One of the few non-social insects to show maternal care — females guard and clean their eggs, and feed hatchlings.

💡

Did You Know?

Female earwigs are devoted mothers — they guard their eggs for months, licking them regularly to prevent fungal infection, and continue caring for nymphs after hatching.

Spine-Tailed Earwig

A slender earwig found in cornfields and grassy habitats across eastern North America. It shelters in the leaf whorls of corn and other tall grasses.

💡

Did You Know?

Farmers consider this earwig beneficial because it preys heavily on corn earworm eggs and aphids in crop fields.
