Much taken with your C drurella, Dave. Some of the small moths are amongst the most colourful. It bears similarities with a couple of Pancalia which I caught by sweep-net at Bacombe Hill, Bucks, 2 days ago.
A bit too fidgety to photograph easily, but full of metallic colours (and about 6 or7 mm long). However, I'm not sure which of the two species I've got; probably leeuvenhoekella (spelling?), but the signs seem a bit ambiguous. Anybody who would like to share an opinion would be very welcome.
At the same time I came across a Stephensia brunnichella, another moth with metallic markings - and even smaller:
Knocked out of a Juniper bush was the following caterpillar:
A Common Footman larva. Probably feeding on lichens on the bush - but there is now some debate about what else they will eat. Juniper itself seems unlikely.
