Well I think it might be. I spotted it on a cilantro flower bud. Sorry for the poor image quality.
It has that line like a sunflower seed down the middle of the back that fireflies usually have but there wasn’t a clear yellow border around the red of the thorax. And it was tiny — whorl on fingerprint tiny. Maybe some kind of soldier beetle? Maybe it just isn’t mature? It showed no fear of me at all.
