Anyone know what kind of bugs these green guys are? They pretty much destroyed the flower head of this sunflower, and I have seen the bugs in other gardens, too. I checked the Minnesota Extension insect site and my guess is it is some kind of aphid. That makes sense in that yesterday I discovered a batch of these creepy red aphids on black-eyed Susans in the front garden. My usual attitude toward bugs is disdainful tolerance, though I removed the stalks of the black-eyed Susans, since they were spent anyway.
