what is this bug?!?!?!

i found this little worm making a cozy little nest by folding my hop leaf over and sealing itself inside in a web type cocoon. i already killed the worm:rockin: but he wasn't terribly big, probably a quarter inch long with a tan body and black head. Does anyone know what this could possibly be and is this the culprit that has been munching on my leaves? Thanks for any input guys... i put an attachment so im hoping yall can kinda see what it looked like.

Probably one of the many types of leaf roller or skipper caterpillars.
