Mottled Beauty.
(Alcis repandata)

After release from the moth trap - on the red pavé garden path.

Information:
Fore-wing length: 19-26mm and quite similar to Willow Beauty and Satin Beauty. Although very variable in colouring the Mottled Beauty has a generally 'wavy' look to the dark cross-lines on the fore-wing and a distinct dark, but blurry edged, crescent cross-line from the leading edge. The outer edge of the hind-wing is also 'wavy' unlike the somewhat smooth curve of the outer edge of the fore-wing.
They fly from June-August and can be seen in almost any location, town or country, in Britain that has bushes and trees.
