I would sprinkle Diatomaceous Earth on them ........if you want to get rid of them They look like some sort of aphid to me.  I have found that DE will get rid of them temporarily on my vegetables but when new growth comes out the aphids end up on the parts without DE.... I have heard that Chickens will eat them
 Good Luck
