British leafhoppers, Cicadellidae, Eupterycyba jucunda, Italian Alder, leafhopper, leafhoppers on Alder
I just happened to be examining the leaves of a local Italian alder tree on Saturday (looking for signs of the Crypturaphis grassii aphids I found on this tree last December) when I spotted first one, then another, then several more leafhoppers, all with quite distinctive markings so, of course, I took photos. When I later checked the British Bugs website, I was able to identify them as Eupterycyba jucunda, a new species for me.
The website notes that this species is ‘found predominantly on alder in England and Wales, as far north as Lancashire’, and that the adults can be seen between July and October. Looking at the photos on the website, I think the small black-and-white objects I also saw (photos below) are actually the empty exuvia of Eupterycyba jucunda nymphs. Fascinating!
