Baeopelma foersteri
Family: Psyllidae
(Formerly: Psylla foersteri)

Baeopelma foersteri is very similar to Cacopsylla and Psylla, but differs in the genitalia and other subtle features. The female terminalia are very long, with the flat apical section finely toothed on the upper surface. The genal cones are unusually short and rounded, the head short and wide, and the antennae unusually long. Pterostigma short. Unlike the even larger Psylla alni, which also occurs on Alder, the forewing veins are pale.

At least locally common throughout the UK on Alder (Alnus glutinosa); apparently most common in eastern and northern England.

Compare Psylla alni.

Adult: June-September
Length ~4 mm
