Currently they look a little like something from a horror movie when you look up close! I've never seen them at this stage. Is it in between the long black things and the final beetle?

The progression is egg, larva, pupa, imago (adult) for beetles, flies, butterflies and other complete-metamorphosis insects.

I saw a huge cluster of ladybird beetles, all in various stages of metamorphosis, and I recall it looked like there were several different forms to this pupa stage - some shorter, some longer, and some looking very close to the final beetle but still segmented. I always wished I could find another cluster like that and photograph it, getting them all in one shot.

The cast larval skin at the base (tail) of the pupa sure resembles a Harmonia axyridis. Thanks to your clear shot, this might be the first confirmed pupa stage we have of that species for Bugguide.

They were still there when I checked yesterday; if they're still there this evening, I'll see if I can get any better shots. Or maybe they'll be at a different stage; we'll see!
