Just another Weeping Cherry tree bug - but which?

Hi folks,

I've attached a pic of what I assume is larvae of some sort. I found it by unfurling a weeping cherry tree leave -- not all the "furled" leaves had a critter -- but a few did.
This lively fellow is about 1/2" in length (the thing in the picture is a twisty-tie for a bag of bread or rolls).

Can anyone ID it? Should I keep it away from small children? Kidding. I'm in the US Northeast where it has been unusually wet and somewhat cool this spring/summer. The WC seems to have more of this wrapped leaves symptoms then usual. Hence my curiosity.

thanks, Bryan

 

These are called leaf rollers. Damage is limited to rolling and chewing you see. A whole bunch of them on one tree could certainly have an impact on its appearance.

 

Thanks for the ID!

So, not necessarily a fatal threat? Would something relatively benign (like Insect'al soap) be a reasonable remedy?

thanks again, B
