It is a true looper, with only two pairs of prolegs. When disturbed, it sways slowly from side to side. It has been found feeding on a wide variety of plants:

  • Roses ( Rosa odorata, ROSACEAE ),
  • Camellia ( Camellia japonica, THEACEAE ),
  • Avocado ( Persea americana, LAURACEAE ),
  • Mandarin ( Citrus unshiu, RUTACEAE ),
  • Senna ( Cassia, CAESALPINIACEAE ),
  • Castor Oil (Ricinus communis, EUPHORBIACEAE ),
  • Wattles ( Acacia, MIMOSACEAE ),
  • Lemon-scented Tea Tree ( Leptospermum petersonii, MYRTACEAE ),

    and is sometimes a pest on :

  • Macadamia Nuts ( Macadamia integrifolia, PROTEACEAE ).

    Pholodes sinistraria pupa

    It pupates without a cocoon under the soil, taking up to a year for metamorphosis. The pupa is dark brown and has a length of about 1.5 cms.

    The adult moths have a wide wingspan (male 5 cms., female 6 cms.) for their body length : 1.5 cms. The wings have scalloped edges, and wavy patterns of light and dark brown. The overall colour is quite variable, sometimes being nearly black all over. The moths normally rest with wings flat and all four wings exposed.
