The Caterpillars have sparse grey hairs, and are black with orange spots and broken cream lines along the body. They feed on various plants from BORAGINACEAE such as:

• Octopus Bush ( Argusia argentea ),
• Salvation Jane ( Echium plantagineum ),
• Heliotrope ( Heliotropium arborescens ),
• Forget-me-not ( Myosotis arvensis ).They grow to about 3 cms. The animal then pupates in a loose cocoon spun in the leaf litter on the ground below the foodplant.

Each hind wing is white with two black spots and an irregular black margin. The moth has a wingspan up to about 3 cms.
  
  (Specimen: courtesy of the Macleay Museum, University of Sydney)The adult moth is superficially similar to Utetheisa lotrix, but there are subtle anatomical differences, and the pattern of pink and black spots is different. In particular, there is a red spot at the tornus of each fore wing ( Roger Kendrick). Also the males have a fold along the inner margin of each hindwing covered in hairs which appears to hold a pheromone.
  
  Kiribati 1980The eggs are pale green and laid in a row on a leaf tip.

  The species occurs widely in the Indo-Australian region, including :

• Borneo,
• Hong Kong,
• New Zealand,
• Papua,
• Seychelles,and much of Australia, including
• Keeling Islands,
• New South Wales,
• Norfolk Island,
• Queensland, and
• Western Australia.

Sometimes it is listed as Utethesia, but this is a misspelling made by Moore in 1860.
