Does anyone know what these are, or if they are good or bad bugs? They are all over my tomato plants!!
Aphids which have been parasitized by tiny helpful non-stinging wasps.
Good news! You have active biological control at your place.
So these are good bugs?
Yes, good guys!
Well, to be more precise -- the good guys are the tiny non-stinging wasp which laid an egg in the aphid.
