I found two of these on our young Red Sunset Maple that we planted in the Spring. They are about 2.5 inches long and looks like the critters used parts of leaves to camouflage themselves.
Thanks for your help.
CLOSED: What type of cocoon is this?
harveyshot,
that is the larva (caterpillar) of a Bagworm Moth in the family Psychidae. All the moths in this family have caterpillars which build a camouflaged bag around themselves, expanding it as they grow.
It is hard to identify individuals from the bags, but your looks quite like the bag of the Evergreen Bagworm Moth - Thyridopteryx ephemeraeformis: http://bugguide.net/node/view/75794/bgpage

Good to know. Thanks!
if you only have a few, you can take them off by hand and dispose of them but if you have more, use a borer and bagworm spray like fertilome's. it has spinosad, an earth friendly pesticide, in it.
Thanks, trackinsand, but there are only two and I was planning on letting them go to fruition. I get a kick out of Mother Nature at work. Bad idea?
bagworms are never a good idea. they turn into moths which in turn turn into more bagworms. a heavy infestation can kill a mature tree.
Bad idea. There is nothing redemptive about this species that I am aware of.
Ok and thanks all. They are doomed.
