Help with insect identification: on tomato plants

[Forest Hill Climber]

I would appreciate it if gardeners and allotmenteers could have a look and let me know what the critters are in the picture. I haven't seen these in previous years.

Thank you Sue. But are you certain? I've looked at several pictures of early-stage Harlequins and they look more elongated than the guys in my own picture.

Shield bug nymphs

I'm not certain, of course, because I just asked ChapGPT, which is not 100% reliable.

I have never seen them before.

I asked again, and Friernlocal is right!

Thank you. I have seen shield  bugs around for several years, just never the nymphs. I'm guessing it's the Common Green Shield bug variety, but possibly the Southern Green shield bug.
