Tubular Lint like or Dust like bug Grey in color - Tinea pellionella

Tubular Lint like or Dust like bug Grey in color - Tinea pellionella
Milwaukee, Wisconsin, USA
February 16, 2011
Size: about an inch
I found this bug on a wall in the bathroom and wanted to know what it was. What is this and is it harmful? It was very small I thought it was a piece of dust or lint and then I discovered that a creature was inside of the tube shape. kind of like a snail. The image shows this better than I can describe it. I have never seen anything like this before. Where did this come from? Is this harmful to pets?

Moved from ID Request.
I unchecked "female" and checked "immature".

Gender
why is this insect marked as female?

Hmm...
I'm thinking it looks a bit like the Casemaking clothes moth (Tinea pellionella):



Charley Eiseman or one of the other experts should be able to say for sure. Even if my ID is a bit off, I can assure you that this is not an insect that will harm you, your children or your pets.

I agree...
I don't think there's another option for a moth larva wearing a straight-sided, portable tube of lint.
