Small mothlike invertebrate, mostly brown.
No interactions present.
Michael may well be right but to me the markings don't look quite right...
Thought it would be a little early for this species also, but if Michael knows the species well, I have no grounds to doubt him.
I agree that the markings are not typical, but I have seen many different forms of this species illustrated, and it is indeed about in numbers at present. It always emerges earlier hereabouts than the books indicate.
There is a good selection of photos at: www.lepiforum.de/cgi-bin/lepiwiki.pl?Pyrausta_Despicata
I'm sure you're right, just not a species I've come across.
