Bug: Harpocera thoracica

My local park railings have produced the goods yet again, this time in the form of three nymphs of the same bug, Harpocera thoracica. I found that a little surprising but a bug expert on social media pointed out that these nymphs can usually be found just as the leaves of Oak trees are uncurling, and the tiny nymphs are so light they get blown out of the trees by strong winds.

There are Oak trees growing next to my park railings, and the day before I found these, it had been blowing a hoolie, so the scenario fitted perfectly. And the nymphs are tiny; that’s one of my fingers in the shot below. I was trying to stop the little creature scurrying over the edge of the railing before I got a picture.

I’ve only seen an adult Harpocera thoracica once. I included a photo of it in a blog a few years ago (Gone insecting, June 2021), but I thought I’d include that photo again here. As you can see, they look totally different to the nymphs. And now I’m motivated to spend some time leaf-fossicking in local Oak trees to see if I can find any more.

Homoptera nymphs, insect nymphs, insects on Polypody, nymphs on Polypody, Polypody fern

During yesterday’s walk, I was looking for a particular species of fern (I’ll explain more about that in a future post) but got sidetracked for ten minutes or so when I spotted this Polypody (not the species I was searching for).

The larvae of a couple of species of moth can often be found amongst the sori, the small clusters on the underside of the fronds where spores are produced, but that is not what I found when I checked these fronds. Instead, I saw several of the tiniest insect nymphs I’ve ever seen. I’m not sure if they were feeding on the spores or just finding shelter amongst them the sori.

They are undoubtedly too small to identify but, to my inexpert eye, they look to be a species of Homoptera, i.e. some kind of leafhopper or planthopper. I’ve already made a note in my diary to go back for another look in a week’s time to see how they are developing, if I can re-find them.
