I found this thing hanging from the framework of my garage yesterday:

...and I think if may be one of these:

The size of the object in the picture was about .75 inches tall by maybe a quarter inch wide. This was taken yesterday in a suburb of Jacksonville, Florida, US in late evening (8:30 pm?).

He was (apparently) using his mouth-parts to draw in what appeared to be a strand of spiderweb, and in about 10 minutes had drawn himself upward, towards the top of the garage framework, a total distance of about two feet.

An additional question would be what is that he's in, a cocoon? a piece of bark or something being used like a hermit crab uses a scavenged shell?

Any help would be appreciated!
