British woodlice, Common striped woodlouse, Philoscia muscorum, Porcellio spinicornis, woodlice, woodlouse
I’ve been leaf diving again, just ten minutes spent picking up and thoroughly examining soggy Sycamore leaves during one of my local walks.
So well camouflaged was it that I almost missed this little mini-beastie, which I initially thought was a Common striped woodlouse (Philoscia muscorum) but, on closer inspection of its antennae, I now think must be Porcellio spinicornis. According to the Naturespot website, the distinguishing characteristic is the number of flagellal segments at the tip of the antennae: Porcellio spinicornis has two, while Philoscia muscorum has three. If I’d known this at the time, I would’ve taken better close-ups but I’ve tried to illustrate the differences below.
