A female earwig with eggs

earwig with eggs

A female European earwig (Forficula auricularia) with her eggs. This one was discovered under a stepping stone in my backyard. In "Insects of the Los Angeles Basin (Charles L. Hogue 1993)", Charles Hogue wrote that "this conspicuous earwig continues to be more and more common in the basin since its introduction from Europe sometime around 1930; it probably arrived in southern California form the northern parts of the state." In this picture, the female earwig is staying with her eggs. She will stay with the eggs until they all hatch. According to Charles L. Hogue, "maternal care is highly developed in this earwig. Females are often found in the spring in small hollows in the soil under stones or concrete, brooding over a cluster of eggs or young nymphs."
