Having a bit of a problem this year. I have a small garden pest slightly larger than a green fly but black with 2 clear wings. They are slowly munching their way through the leaves on pretty much everything but seem to like the lettuce and courgette leaves best. Any ideas what they could be and how to get rid of them?
Many thanks

Hello Dave, welcome to Ish, bit tricky to know what this is, would need information such as where do you live in the world and a picture would be helpful
