Abstract

WORKERS in Europe1–4 have maintained that the common earwig, Forficula auricularia L., is single-brooded in Europe, whereas American researchers5–9 have recorded that this species in America has two broods a year. Recently, Bolwig10 reported from Denmark that F. auricularia is single-brooded, and laid a second batch only if the first eggs were destroyed. However, while studying the life-history of F. auricularia in the Department of Zoology, University of Edinburgh, I found the earwig to be double-brooded. The first or winter batch of eggs is laid between late November and March. During May–June some of the females die, and the others lay a second or spring batch of eggs. A detailed account of the investigations will appear elsewhere.
