Llansteffan moths

I've trapped a few times but not had many moths to write about, but this turned up on my net curtain in a north facing window, I imagine it has over wintered on my house plants! But I have a vague recollection of picking a furry caterpillar up last autumn and putting it in a box with other caterpillars that didn't over winter well. It may have escaped as a moth and landed on the curtains while trying to make a bid for freedom. Anyway my first Ruby Tiger of the year.
