I've noticed some aphids on a few of my Hoyas lately. They are bright yellow with black legs. I looked in the BugFiles and found the milkweed aphid, which seems to be what I have, but I'd like confirmation on that.

In the comments it states that ladybugs can suffer wing damage from eating these particular aphids. On another Hoya, which interestingly does not have any aphids on it, but is next to one that does, I found a ladybug with deformed wings. Are the aphids the cause of this?

Here are the aphids. What is the dark gooey thing? It seems to be on the ones that are infested. An eggsac, perhaps?
