Jo, notice how 5117 has a striking white head and palps. This one reminds me of a worn Rotund Idia Idia rotundalis 8326.
Checked that one too, Stu. You are most likely correct so I will edit. The description for 5117 mentions that the head and labial palps are pale yellow,hence my query as to possibility of same.
Brown Angle Shades is here in numbers this evening at bait. There is one Sharp Angle Shades at bait as well.
