I walked outside this afternoon to find some very confusing looking ‘yellow balls’ with odd pointy black bits on my butterfly bush. After some minor research, it turns out they are Oleander Aphids. I saw you only have one photo of the little weirdos, so here is another! They apparently do not harm the plant, so they get to stay there.

We get Oleander Aphids, Aphis nerii, on our Hoya lanceolata each year. We do not believe they are harmless as they suck the sap from the host plant. We spray them off the Hoya with a hose.
