I'd never knowingly seen one before and I'm near certain it's a plant bug. After taking several shots I nudged it carefully hoping it would move so that I could get a new angle, but it remained motionless and I left. I returned a bit later to find it had moved to a different flower head but because it's such a flat little bug, the same problem existed. It's color appeared to be solid beige to the eye. Only on my iMac did its speckled pattern become apparent.
