Japanese Earwig

A montane earwig found in the mountains of Japan, known for extreme maternal care. Females guard eggs and first-instar nymphs in burrows under stones.

💡

Did You Know?

Japanese earwig mothers sacrifice their own bodies as food for their young — the nymphs consume the mother after she dies.

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.
