Abstract

The life history of the European earwig at Vancouver, B.C., is described and divided into two periods: the nesting phase and the free-foraging phase. Seasonal changes in population characteristics are documented and compared in sparsely and densely vegetated habitats. The developmental rates, population sizes, and sex ratios, but not the body weights, differ between the two habitats. Suggested reasons for these differences are advanced.
