The Caterpillar is off-white, with a dark brown head, and with brown marks on the segments of the thorax. The caterpillar lives in a silk case covered in small bits of detritus. The caterpillar appears to feed on any animal material. The caterpillar refuses to eat any sort of vegetable material. So the caterpillar has been found feeding for example on:

  • dead insects,
  • wool and fur clothing, and even
  • pigeon dung.

    The case reaches a length of about 1.2 cms. The caterpillar pupates in its case. The pupa is pushed partly out of the case for the adult moth to emerge.

    The adult moth is has forewings that are pale brown speckled with dark brown, each forewing having two vague dark spots as well as a subterminal arc of dark spots. The hindwings are a satiny brown. The wingspan is about 1.2 cms.
