Idiocerus tremulae
Family: Cicadellidae

Leafhoppers in the Idiocerinae are large and often highly patterned, with a very broad, short vertex. The group is large and often very difficult to identify. Almost all are associated with poplars or willows.

I. tremulae has an extremely prominent transverse dark band on the forewings, distinguishing it from most species. The face is pale in males, and normally chestnut above the level of the ocelli in females. The thyridia are pale in both sexes. Forewing veins are dark apically and there is usually one or more pale longitudinal streaks on the pronotum. Males lack antennal palettes.


Relatively local, on aspen or white poplar, in the southern half of England and Wales.

Adult: July to November
Length 5-6 mm
