Casemaking Clothes Moth

Casemaking Clothes Moth

 Adult casemaking clothes moths are approximately 3/8 to ½-inch from wing tip to wing tip, and are slightly smaller than webbing clothes moths.  The wings and body are buff to golden with a brown tinge and the front wings have three dark spots, but these distinguishing characteristics are often rubbed off.
 The larvae are small caterpillars (3/8-inch long) that live within a small portable, silken case which they carry as they feed.  The larvae have dark head capsules and the first thoracic segment (leg bearing segment) is dark brown or black.
Females begin laying eggs (37-48) singly on suitable larval food the day after emergence as an adult.  The larva feeds for about 33-90 days and molts 5-11 times.  The mature larva then finds a sheltered place to pupate. The insect pupates within the silken larval case.  Developmental time (egg to adult) requires 46-116 days.  The casemaking clothes moth is usually more common in the southern states where there are two generations per year.  Adults may lay eggs year around in the northern states but have only one generation per year.

The casemaking clothes moth prefers products of animal origin, secondarily feeding on products of plant origin.  It is a pest of woolens, rugs, feathers, felts, skins, spices, drugs, furs, taxidermy mounts, and stored tobacco.  The larva remains within the case at all times and dies if removed.  It can turn completely around without leaving the case and can feed from either end.  Adults do not feed.

Casemaking clothes moths shun light, and although the males are active fliers, the females fly only short distances.
