What is causing this problem? I noticed it after an extremely hot day. All the new growth is normal. It is raining out, so not sure if the little white bugs caused this (didn't notice them before) or if they are taking cover from the rain. It seems that it is only affecting my Parkland Morden Roses. Hybrid Teas, Floribundas and other hardy shrubs are fine.

Those leaves do look more eaten. Perhaps someone will have seen these little critters before. I still have no idea.

It's the little hopper whiter bug. Some roses in the back yard are now affected and not raining and the bug is there. Wish I caught it sooner

Do you mean it is a type of leafhopper?

They look like white fly eggs and larvae. No idea where the adults went, but the leaves look like they have some kind of sucking insect damage.

I'd go after them with the soapy water spray asap.

They look like White Fly from the images, not Giant White Fly. They are all over the hollyhocks. I never see them on the roses, but that doesn't mean they won't or can't feast on them. The foliage appears to have had the sap sucked from it, like spider mite infestation, which the white fly can do. If you have large leafed perennials or annuals around, check their foliage for them, too. Insecticidal soap or horticultural oil sprays can knock them down as long as it is applied to the reverses of the leaves.

Sprayed the entire garden with Insecticide soap. Hope the the plants recover. Note: I usually don't take such drastic measures, but I have committed to a large group for a open garden on Aug 11 and those little bugs have done a lot of damage on many roses.
