I found this bug working its way across my laptop while I was working at night. It doesn't look like it has any legs. It is about 1/4" to 1/2" in length. It is like a little gray/brown tube and when it moves it extends this tongue like thing to pull itself forward (or backward because it can extend from both ends of its body).

It's a very strange creature :) I'd like to know if it may be the thing responsible for some rather hideous bites I've been getting while I sleep (I thought they were ant bites, but rather severe).

I posted a video of the bug in action: (it is inside a SDHC mem card container, so you can see it is quite small)

!! Sorry I don't have an answer but that thing is crazy!!

Sorry, don't have a clue but it's the creepiest thing I've ever seen.

I'm not even certain that it is an insect. The motion reminds me more of a snail or a mollusc.

Further research suggests that it may be a very young bagworm. Look at this and see if it's similar:

This looks like a household casebearer, also known as a plaster bagworm.

Household Casebearer, Phereoeca uterella

Yep, that's pretty much it. Thank you :)
