Mocydiopsis attenuata
Family: Cicadellidae

A small genus of two deltocephalines which requires careful separation from Mocydia crocea.

The two species are hard to separate, and females can be indistinguishable.
The male anal tube (final abdominal segment) is much longer in M. attenuata, nearly as long as the rest of the abdomen. The presence of a dark spot and other mottling in the clavus also identifies M. attenuata The facial features (below right) are shared by both, although M. parvicauda may lack the stripes and the dark patches near the eye.

Both species occur locally in grassy areas in southern Britain with M. attenuata preferring more calcareous habitats.

Adult: July to October
Length 3.8-4.5 mm
