Found it, at U Idaho. http://image.fs.uidaho.edu/vide/descr840.htm But I would be fooled by reading the description and then looking at Petes plants. Peter Whiteflies and control, we have 3 species in the Northeast, One is called greenhouse whitefly. This one emerges just as soon as the greenhouse thaws out. The other 2 just as soon as the ground thaws, and don't disapear until the ground freezes again. They are about the same as aphids, very rapid reproducers, But they will also suck on almost any plant. When you think that you have them under control the next light breeze brings more.
