So named because the larvae carry their pupal cases about as they feed and travel, case-bearing moths are much less likely to be found in your home than the Common Clothes moth.
Look for the faint, dark smudges on the wings of the adult. The wings have a very slight, darker, dusky appearance, compared with the clothes moth, giving it a slightly dull appearance. The eggs are visible only under a low-power microscope. The larva of the Case-Bearing moth is much more easily identified because of their cases, open on one end, and dragged about, wherever they go. The larvae only expose the first few segments, staying within their case for protection.
The larvae never leave their cases, and when ready to pupate, will seal off both ends of the case, and when the adult finally emerges, they cut through the end of the thin silken case. The Case-bearing moth is usually found around carpets and heavy woolen draperies. Case-bearing clothes moths are not that economically important, certainly not as much as the common clothes moth.
