Wasps, bees and spiders don't eat roses. Grasshoppers do and so do some caterpillars and other little creatures. That, however, won't cause your roses to droop and wilt. Are you watering enough and putting mulch around your roses to keep their roots cool? Gopher activity can also affect rose bushes since they eat the roots.

I don't use any poisons and don't spray, but usually birds will kill off whatever is eating the leaves before they do too much damage. The wilting is more worrisome, so I'd try watering more and making sure you have enough mulch around your rose plants.

Leaf cutter bees?

That doesn't look like leaf cutter bee notches. Leaf cutters make a little smaller notch and completely encircle the leaf. You should see some of my rose and peony leaves. These are an important pollinator in this agricultural area, and the farmers even rent them to pollinate certain crops. They do a real number on rose leaves. Diane

If you live in Houston and you're planting new roses in late July and they droop and wilt...

The insect damage shown in your photo is not going to damage the plant. You need to provide shade cloth for your rose and water deeply several times per week.

I would say the drooping is due to the heat. I just put in a few last week and they were pretty droopy too. I snapped off the buds and made sure they had plenty of water. We had a soaking here last weekend (and yesterday also), but the new roses were still wanting water by Thursday because it's been hot enough to dry out even the marshiest area. Supposed to be hotter next week, so I would just keep up with the water. New roses don't have the large, spread out root system that established roses have, and they need more help.

Check with someone from the Houston Rose Society. They all live in you're general area and should be able to help you, one on one.

I live in east Texas, 2 hours from Houston. After spotting this bug at night while I was outside near some lights, I found that the June Bug, which is common in our area this time of year, was the culprit who had been chewing on my roses. I use an insecticidal soap spray, cant recall who makes it, but you can get it at Walmart, Lowes. Spray on buds, leaves - this should stop whatever is chewing. As for wilt, the above posts are correct. If you have just planted your roses, they may exhibit wilt for a few days - just keep them well watered - and make sure you didnt plant in a hole that retains water - this can make them wilt. I read on the forum that it is really good to disbud for awhile, let the roses work on growing roots, not blooming. I now disbud all my newly planted roses for a couple of months. Maybe even prune them back a bit so less plant to have to keep moist. I usually prune my roses back a bit before planting. Also, just the heat itself might make them wilt until they get established. Just give them some time, they will probably be fine. Good luck!
