My epic discovery of the day - the plaster bagworm moth larva / household casebearer

Ever since I could remember I was always curious as to what these creatures were until today upon seeing one on my bathroom wall I decided to ask my friend Google what it is. Finally after trying so many search terms (ex. weird, small, leaf, shaped, worm hanging on wall, in sack, climbing, poking head out, etc) I finally learned what it was!
The larva actually spins a silken case open at both ends. In order to move, the larva pokes out of these holes to attach itself along light colored walls.
