Sounds a lot like the white flies that seemed to be taking over southern
California a few years ago. They mostly stayed on the undersides of leaves.
Brushing against a citrus tree would set a humongous cloud flying around

Few chemicals did much of anything against them. Within a couple of years some
natural preditors of theirs were introduced (one was a teeny wasp, as I
remember), and they soon were under control (but not eradicated).

The particular kind of whitefly we had did not show much interest in iris, but
the MO sounds about the same.

I hope my guess is wrong. These beasties were bad news.
