Okay, I was walking around this morning and notice these guys on my butterfly weed. I am used to seeing aphids and Assassin Bug nymphs on these plants, but can't say that I have seen these guys before.

They don't look like Aphids, but I am wondering if they are mature Assassin bugs that are dining on aphids. Geez, I hope so because they looked really yucky.

Anyway, can some one tell me for sure what they are.

Thanks.
