These Caterpillars live in cases composed of one, two or three stiff chambers made from hollowed-out flower buds or seed capsules, each like an inflated cube. The caterpillars feed on the flowers of

  • Bottlebrushes ( Callistemon species ), and
  • Paperbarks ( Melaleuca species ),

    both of MYRTACEAE. <

    The case can grow to a total length of about 1.2 cms. The caterpillar pupates in its case.

    The adult moths have pale brown heads, and off-white forewings each with grey speckles which coalesce in places to form several vague dark transverse bands. The hindwings are plain grey. The grey fades to brown in dead specimens. The wingspan is about 1.2 cms.

    The species occurs in Australia in:

  • Queensland,
  • New South Wales,
  • Australian Capital Territory,
  • Victoria, and
  • Tasmania.
