These seem very common on nettles
No identification made yet.
No interactions present.
The photograph shows a spinning made by a caterpillar and the black specks are its frass. There could be caterpillars still present in some of the spinnings. If you could find and photograph one of them, it might be possible to give an ID.
Thank you so much for your comment. I am quite new to looking closely at wildlife. I did find a caterpillar on nettles where the frass was present. I'll upload the picture of the caterpillar. However, I am not sure whther it was the same one that left this particular clump.
include Mother of pearl Pleuroptya ruralis, Nettle tap Anthophila fabiciana and Snout Hypena proboscidalis
Thank you! This is quite important as I am trying to bring across the value of nettles for wildlife.
There is an excellent little book: http://www.amazon.co.uk/Insects-Nettles-Naturalists-Handbook-B-N-K/dp/08..., if you don't know it already, may be of some interest.
