...been doing a bit of online research into the leek moth / onion fly problem and found this really good blog.

I've definitely found the cocoons of the leek moth but I do suspect we have onion fly too. Interesting to learn via the blog (with posts starting in 2008, running through to this year) that the leek moth first only affected the south of England and has been moving north. I know a lot of Norwich plots which had it bad last year....

My squishing / removing of affected leaves seems to be working ok, though it's only been a few days. There are supposedly several generations per season of onion fly!
