Hi flaflwrgrl,
Well, here's what I know and it's sadly all I can find out now that high winds came through and toppled my jar.
First the cover came off and I found this beetle in there. Now, I'm not sure if it flew in there or it came from one of the black pupaes. There were also several of these much smaller little flying bugs. SO, now I'm wondering if they were two completely different things going on here! I'm going to mull it over with Janet and see what she thinks.
