The cerci of the adults can be used to distinguish the sexes. In the male the cerci are more curved, with the right branch of the forceps turned sharply inward at the tip. The males also possess 10 abdominal segments, whereas females possess eight segments. Doru earwings have wings, including tan colored bands on the prononum and front wings. They are important caterpillar predators.
Earwigs are nocturnal.
Mating occurs one to two days after attainment of the adult stage, and oviposition commences about 10 to15 days after mating. The adults construct a small cell in the soil in which eggs are deposited. The female drives the male from the oviposition chamber before eggs are produced. The female protects the egg clutch from mites, fungi, and intruders, cleaning and relocating them if necessary. Maternal care decreases soon after nymphs hatch, disappearing after about 10 days.
