Katydids. This time of year they look like deiicate green grasshoppers but without wings.

Bayer 3-in-1 will get rid of some of those bugs. It will also kill the predator wasps, ladybugs, and any mantids and create an environment where the bad bugs return sooner than their predators. For those aphids, rose slugs, and mites, a simply spray of water is nearly as effective as a kill'em-all insecticide. These are the easier of the pests to knock off of rose bushes. The rain should be part of your pest control, and not contributing to the infestation. I believe all of the ones you listed prefer hot & dry conditions.

This happens to my roses like 2x a year. I cannot explain what causes them to form this way, but it seems to affect many different varieties and usually around the same time. Some varieties (elegant fairy tale, sugar moon, mr Lincoln)are more prone to it than others. I live in south Fl so cold or frost damage is certainly not the culprit. I read once that too much alfalfa can cause this to happen, and I think there is a coorolation because one year I used copious amounts of Rose Tone (which contains Alfalfa) and that was the year that I had it the worst. (I no longer use rose tone and I've seen a significant decline). Not to say that Rose Tone is bad, I believe it to be a good product, but I used it in pots and perhaps it was too concentrated. Have any if you seen a cooralation between using alfalfa meal and phyllody (or near phyllody) like Hoov says?

Those are bagworms. Unusual for them to attach themselves to roses, but not unheard of. Usually they are most common on Junipers or Arborvitaes. In my area (Tulsa) they can start gathering their bags in late April or May. They start out very small, and as they eat and gather leaves they grow much larger. My evergreen Arborvitae is prone to them so every few days when it's time for them to show up in late spring I start checking the foliage to see if the small ones are starting up. B.T. will kill the small ones, not so much the larger ones. I've supplied a link to an Oklahoma Master Gardener site about them...Hope this helps...Maryl Here is a link that might be useful: Oklahoma bagworms
