Extract

The biology of Praunus flexuosus (Müller) is closely similar to that of P. neglectus (G. O. Sars). In both species the over-wintering population matures and breeds in the early spring and summer to produce a spring generation of young which are evident in the population in May or June. The members of the over-wintering population die off in July or August. Some members of the spring generation become sexually mature and breed in the early autumn. The progeny of this autumn breeding, along with the bulk of the spring generation, form the over-wintering population. These species are omnivorous feeding on animal and plant debris and also preying on small crustaceans, very frequently harpacticid copepods. The maximum brood size found in P. flexuosus was 63 and in P. neglectus was 81. The biology of the populations on the west coast of Scotland is briefly compared with that of populations in Port Erin, Isle of Man, in Norway and at Roscoff.
