|A BIT ABOUT BUGS
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. avellanae is generally pale yellow but at least sometimes shows an intense yellow colour on the basal two-thirds of the forewing. Identification requires dissection; the distinctive aedeagus has only two prongs, forming a smooth, U-shaped branch.
Found widely across the UK, on hazel. Has also been found on other trees, including elm and sycamore.
Adult: June to October
Length 3.5-4 mm
