Went out for a sprig or two of parsley, and was horrified to see these buggers greenfly, on some of last year's plants. They were just on the newly growing seed-heads' stalks, rather than the rest of the plant... i.e. not on the sprigs for my dinner! I let at least a couple of plants go to seed, and thereby keep the crop going.

I hope the cavalry (Ladybirds) arrive soon!
