I didn't get any reply on another gardening forum, so I'll re-post here to PBS.... ---------- Forwarded message ---------- These little guys wiped out many plants in my collection last year. And they're back this year. The best I can figure is they're some kind of foliar thrips, if there is such a thing. What do you guys think? Nematanthus brasiliensis http://www.badbear.com/P9030010.JPG http://www.badbear.com/what%20is%20it%201.jpg Niphaea oblonga http://www.badbear.com/P9030013.JPG http://www.badbear.com/what%20is%20it%202.jpg They wiped out a bunch of my baby AVs already, before I realized it was actually pests, and not overwatering making my AVs sick. Ugh. They seem to love Geseriads, Begonias, Amaryllids, Orchids, but not so much Irids, or Passiflora. Thanks. Dennis in Cincy
