This one was hard to identify. On the basis of the wing pattern I initially thought it was a Bloxworth snout [Hypena obsitalis] but the head is wrong - no snout ! After consulting with the regional / county moth recorder, what I had here was a Common Marbled Carpet [Dysstroma truncata] but with one of the rarer variations in colouring. [2 of 4]
