Well that's certainly informative. Some years back I had a major infestation of what was probably the soft brown type--copious amounts of honeydew; that was what caused you to notice it. It was encrusted all over my houseplants like jade plant and aloe vera. Had small kids at the time, and probably wasn't very vigilant!

Anyway, I thought they all looked like that. But this pest has many faces. Yuck--I'm feeling itchy all over just thinking about it.
