Materialized mysteriously on my cell phone display (nice flat background for the portrait, anyway) and was nearly accidentally killed before I realized it was alive and not just random schmutz. Currently residing on a denim rag in a plastic tub, to see if he/she survives long enough to become an adult. Based on pictures online, my guess is that this is a larval case-bearing clothes moth, but would appreciate confirmation.

Canon 5D m4 w/ 65 mm, 1-5x probably at 3 or 4X, ISO5000, 1/160, f9, ringflashed
