Caterpillar eating my roses - Allantus cinctus

Moved

Yes,

certainly the curled rose sawfly, Allantus cinctus (Linnaeus, 1758). Larvae of two other rose feeders are very similar, Allantus nigritibialis and Allantus viennensis, but these haven't been recorded from as far west as MN.

Curled Rose Sawfly?

Did you see curled like this?
If so, I think that's Curled Rose Sawfly larva :)

If not curled, other sawfly larva?

curled rose sawfly

Some of them were curled up and some were elongated while eating. Did they come with the Roses? In the root ball or do the sawflies just find the roses after you've planted them? Also, some of the leaves had cottony white tufts stuck under them-were these some sort of egg sacks?

They find the roses.

The cottony white tufts may be shed skins from the sawflies growing, or they could be another pest. Here is an extension page you can check out:

Not a caterpillar, but a sawfly larva

Looks like the curled rose sawfly:

How do you get rid of them on your roses?

What a great site this is! I've been asking everyone I know the ID of these guys for years now and they look at me like I have 2 heads when I tell them its a little green caterpillar that curls up in a spiral on the leaf. Neem Oil doesn't seem to be working that well. Any other ideas? Right now I am physically picking them off but they usually win the war. Where is a nice Wren when you need one? Any assistance would be much appreciated.

Here's a link.

That previous one is no longer there, but here is the UMN page on sawflies in general.

As a rule, we are not supposed to give pest control advice. If you have questions I'd recommend you contact your local extension office.
