Hi. We are in central London. Two small moths have appeared in our kitchen. One was black, with a few dots, gold or cream, and it sometimes rested with it's wings wide open, sometimes with them folded up. About 18-20mm. The other (still in the kitchen) is a grey mix, 16mm across, and it always rests with wings wide open, like a semi-circle. We are not equipped to photograph these tiny delicate things, but the photo at least shows the resting shape. We don't know whether to gently evict it or not - there are strong icy winds outside and not much greenery. There are so many micro moths and little moths in the UK - but if anyone can help narrow it down via resting wings position I would be grateful. Thanks.
