Tinea pellionella Linnaeus

[Lepidoptera: Tineidae]


“Infamous for damaging valuable and costly clothes you definitely don’t want these moths getting into your linen or stored clothes. A lot of damage to people’s clothes could’ve been prevented if they took a few simple steps or called a pest controller before things got out of hand. We’re a company that wants to help you as best we can and make sure no pests hassle you.” – Bruce Gow

Adult: Casemaking clothes moths have a 9-16 mm wingspan. The body is covered in brown scales.

Head: The head is large and rounded. Antennae are long and thread-like (filiform). Eyes are small (less than half the size of the head).

Thorax: All legs are similar. The forewings are covered in brown scales with 3 dark spots sometimes prominent. Wings are held at right angles to the body at rest. Hindwings are similar to forewings but have a fringe of hairs on the posterior margin.

Abdomen: Cerci are absent.

Reproduction & Life-cycle:Adult stage from 42-130 days. Females lay sticky eggs with longitudinal ridges on the shell. Eggs adhere to the substrate. Egg stage 4-7 days. Larvae with legs, eyes and head capsule, typically caterpillar-like appearance. The larvae construct parchment-like cases which they carry while feeding and retreat into when disturbed. Larval stage 41-56 days. Pupation occurs in a cocoon formed from an enlarged case. Pupal stage 9-20 days.

Distribution:A widespread, probably cosmopolitan larval pest of hair, hides, feathers and some plant material. More often a pest in domestic homes than commercial facilities.

Pest Status:Adult males are active but females are sluggish. Larvae prefer fabric stained with fruit juices, or containing human sweat or urine for B-complex vitamins contained therein. Larvae can damage but not digest cotton and linen. Development, biology and anatomy resemble the Webbing Clothes Moth but casemaking clothes moths carry webbing and are less common.
