Edwardsiana crataegi
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. crataegi is one of the few that can be distinguished without microscopy.

The yellow ground colour combined with the dusky clavus is distinctive. Unlike E. geometrica, there is no 
oblique dark line along the corio-claval suture.

It is common on hawthorn, rowan and various fruit trees across much of the UK except the far north.

Adult: July to September
Length 3.5 mm
