Earwig

Natural Habitat

Damp, dark places; under rocks, logs, leaf litter, mulch, and sometimes indoors in bathrooms or basements. They prefer humid environments.

Diet & Feeding

Omnivorous. They feed on decaying organic matter, fungi, plants (leaves, flowers, fruits), and small insects (aphids, maggots, mites). Some species are predatory, others are scavengers or herbivores.

Behavior Patterns

Nocturnal. They are typically hiding during the day and active at night. They are known for their prominent cerci (pincers) at the rear of their abdomen, used for defense, hunting, and mating. Some species exhibit maternal care, with the female guarding eggs and young nymphs.

Risks & Benefits

Generally harmless to humans; they do not sting or transmit diseases. Their pincers can give a mild pinch, but rarely break the skin. Can be considered pests in gardens as they can damage seedlings, flowers, and soft fruits, but they also prey on garden pests like aphids. Indoors, they are mostly a nuisance pest but do not cause structural damage or infest food.
