what is this insect on my Rose bushes? How can I eradicate it? Clearly i would not have asked this question if it was not doing damage to the roses!

I don't know what it is either, which is not much use to you, but is it harming the plant? If its not doing any damage, then I'd leave it alone - it might be something that eats aphids, which would be useful.

I agree with Bamboo, it's more benefit than harm, leave it alone.

Is it one of the hover flies? In which case it should be a welcome guest

its a type of wasp species that lives on its stings a largish insect like a spider and lays an egg on it i wont hurt anything including you.if you look carefully you can see the abdoman going down to a point and the antenna give it away to the wasp family to.very close to ants in everlution to as it goes.dont worry im full of useless information lol

Erica, why do you want to eradicate an insect that may just be having a rest on one of your plants?

Nosey is right in that it's a wasp relative (Hymenoptera) but this is a Sawfly, one of the plant feeding wasps. As it happens though, this one actually can damage your plants as it is a Rose Sawfly!

Nothing can be done now but spray with Bug Clear or similar (not Provado as this kills Bees) in late spring next year.

In defence of all those who answered, you didn't say in your original question that there was damage to your roses, nor describe what it was - some people fret about all insects present on their plants, and since most of us did not recognise the beastie for what it was, you could have been one of those people.
