Is the second a Coleophora and if so is it possible to identify the species? About 6-7mm in length.
I assume the third is either Nematopogon schwarziellus or N. metaxella?
For number 4 I think I have been identifying too many of the Scoparia and Eudonia moths that I have caught as S. ambigualis. This one certainly looks a bit different.
