A low-pressure weather system appears to be stuck over Ireland at the moment, so there has been plenty of rain (I blame Wimbledon). That means I have had some time to look at previous identification problems, and I have managed to identify a leaf-hopper that I found in July 2009. It's the Potato Leafhopper - Eupteryx aurata:
Potato Leafhopper - Eupteryx aurata
It's one of the few leafhoppers that have a common name, presumably because it is said to be a pest on potatoes. (It's interesting that the few fungi or insects that have been assigned 'common names' are the ones that we find most threatening. Death Cap and Destroying Angel come to mind.)
Identification new to my species index, which now stands at 1431 species.
