Leafhopper: Issus coleoptratus

A couple of months ago I blogged about a couple of leafhopper nymphs I’d found on the local park railings (Leafhopper: Issus species, 5 May). At the time I was fairly certain these were Issus coleoptratus, and I explained why I’d reached that conclusion but, when I recorded my finds, the national recorder redetermined my records to Issus species.

I’m feeling just a little smug that my earlier conclusion has been vindicated by the fact that I’ve now found an adult Issus coleoptratus just along the railings from where I found the nymphs, and its identity has been verified by the national recorder. Of course, the little leafhopper wanted to run away when I got close to photograph it but then, when I put my hand against the railings to stop it scooting down the other side, rather than hopping away as they usually do, it crawled on to said hand and was very tickly as it wandered around on my skin. It was a delightful encounter with a very handsome little bug.

I’ve found two of these little leafhopper nymphs recently but was waiting for verification from the national recorder before posting about them. I recorded them as Issus coleoptratus but the recorder has changed them to Issus species.

The recorder is the expert, I certainly am not an expert but, in this case, I do think these are Issus coleoptratus, and here’s why. According to the Naturespot website entry for this species, there is only one confusion species, which is the much rarer Issus muscaeformis. Naturespot also includes excellent macro photographs of the identification features to look for on a nymph, which are more than 7 sensory pits on its back and pale horizontal bands on the frons (face), both of which I can see in my photos.

I will just have to look for the adult leafhoppers when they appear between June and November and hope that they will convince the national recorder. Meantime, I’m still really pleased to have found a new-to-me leafhopper species.
