ResumoAbstract Methods for rearing Staphylinus olens (Müller) (Col., Staphylinidae) are described, and development compared with other species of Coleoptera. The distribution of S.olens over an area of Manchester is noted, and biological comparisons made with a laboratory population from South Wales. In the area sampled, most individuals live on well‐drained soils, possibly because successful pupation occurs under dry conditions. ‘Courtship’ and mating are described. Egg‐laying, the egg, and its hatching are described, and compared with other coleopteran eggs. Headwidths of laboratory larvae were recorded, and are compared with those of other beetle larvae. Instars I and II lasted 44–45 days, although first instar larvae which eventually pupated had a mean duration of 33.5 days. Instar III averaged 102 days, but this time became shorter with later hatching, roughly synchronizing adult emergence. Pupation and the obtect pupa are described. Pupal development took 32–37 days, after a 10–14 day prepupation period. Newly emerged adults may construct winter burrows after autumn breeding. Second season adults may not hibernate, and often fail to survive another winter. Food is manipulated by mandibles and legs, but no solids are consumed. Adults and larvae will eat many foodstuffs.
