Mystery solved. Today was an exceptionally nice day here in the Philly area and I was out examining the Euonymus when an unusual ladybug landed on me. Completely black with two red spots. My research revealed this to be a "Twice Stabbed Ladybird Beetle". Further research revealed the larvae: http://bugguide.net/node/view/60789/bgpage

I found several more of these ladybird beetles in the plant- even a mating pair!
Fortunately, they are predators of scale insects. I am interested to see what kind of effect they have on the population of scale(I have a very severe infestation)
