They look like small beetles. Most of the small garden pest beetles have more color, you might check a garden pest guide to be sure.

They're newly hatched nymphs of stink bugs. But which particular one I don't know.

Not to doubt your expertise, but I Googled "stink bug nymph" and found this picture ... which doesn't seem to match my picture.

Look for 1st, 2nd, and 3rd instar pics.

Thanks 'day_by_day' ... I'm obviously not an entomologist ... I had to Google 'instar' to even figure out what that meant. However, I did find a picture that much more closely resembles my pic ... so I now am convinced that my bugs are indeed stink bug nymphs! Hats off to 'jean1000' ...

I'd advise you not to question jean001....she is rarely stumped. ;-)

I agree about Jean, and the antennae in your picture does look stink-buggish.
