very similar to a spidermite infestation that i'm dealing with... i use safer's insecticidal soap, it kills on contact and is biofriendly (smoke safe), but it does not erradicate completely... mites die and are back in a week. and i've one that looks a tad bit worse than that one... i watered, she picked up some, i'm misting lightly, that seems to help too...but i may be fighting a lost battle.

have you seen any webs?

sorry i can't help more...

love, kp
