Gothic.
(Naenia typica)

Not a good photo but just enough to identify this as a Gothic moth.

Information:
Fore-wing length: 17-22mm. A general colouring of dark grey/brown with wing-veins showing as white lines plus a variety of crosslines and oval/kydney outlines make a distinctive and dramatic contrasting network that is relatively easy to recognise.
They can be seen flying June-July in localised areas of Britain, frequenting gardens and damp places such as riverbanks or marshes, as well as hedgerows and damp meadows. They like a wide variety of vegetation such as woody and herbaceous plants as well as buddleia, apple, blackthorn, comfrey and willowherbs.
