For the parasite, although I have never seen them turn black like that
On milkweed. Rose aphids I think
Manestar Tract, St Williams, ON
Not sure what's happening here. It looks as though this aphid is dead. The blackish area could be damage and has attracted the attention of the ant.

Aphid of some sort but the suction cup structure beneath is what is confusing. Any ideas/information?
