I saw this moth on my kitchen window and it stayed there all day, just moving an inch or two down the pane…
I went outside and took this picture of its top side, which i hadn’t expected to be grey-brown
It turns out there was no need for excitement – this is simply the “dark” version of Cydalima perspectalis, the box-tree moth, which I had previously spotted in its paler form here.
This is an invasive species and I have seen far too many examples of this moth lately. At least I no longer have any box trees myself and this particular specimen looks rather worn and missing a few legs. Apparently they are around from late July until mid September, so as this is late October it is probably on the way out…
