Edwardsiana geometrica
Family: Cicadellidae

Perhaps the most difficult of all leafhopper genera, with 21 UK species, of which only two are easily identified; the other 19 cannot be identified based on external features alone.
E. geometrica is one of the few that can be distinguished without microscopy.

A very strikingly-marked species, and the
 dark stripe along the corial-claval suture is diagnostic. The ground colour varies from whitish to yellow.
      
Widespread but not normally common, on alder; perhaps absent from the extreme north.

Adult: June-October
Length ~4 mm
