I found what I think are tiny white eggs with a small back dot in each, on the top of a Rocket salad lettuce leaf and what I thought was tiny dark glossy eggs on the underside..
However when I watched the dark 'eggs' they started moving about, they went onto the top of the leaf and appeared to be checking over the eggs (or possbily farming them?) they did this for some time and then went back to the undersidde of the leaf and clustered together again..
I have scoured the internet and can't find anything that looks remotely similar. I am in Bristol.
Unfortunately they are too small to get a picture of.. Please can you advise me what these might be?
