Guess I was right last time about what those two moths were doing in flight. They now seem to be setting up home in an old water pipe I have in my garden. Most probably I will have to spray the pipe with insecticide to scare them away.
Lovely collage! You seem to have a lovely colony but do not get too close as they are bees not moths. But I just read that this species do not sting and they are very useful pollinators!
