This Caterpillar is usually brown and hairy, although the colour can vary from yellow to black. Whatever colour it is, characteristically it has four pale tufts of hair on abdominal segments 1-4, and also a tuft on its tail, and also two black tufts on its head pointing diagonally left and right like a pair of horns. Behind the dorsal tufts are two red markings, surrounding dorsal glands on segments 6 and 7. The hairs can cause skin irritation ( urticaria ) in sensitive people.

The caterpillars have been found feeding on a variety of plants in suburban gardens including :

  • Dahlia ( Dahlia pinnata, ASTERACEAE ),
  • Cypress ( Cupressus, CUPRESSACEAE ),
  • Lupin ( Lupinus nanus, FABACEAE ),
  • Geranium ( Pelargonium x zonale, GERANIACEAE ),
  • Gladiola ( Gladiolus byzantinus, IRIDACEAE ),
  • Albizia ( Albizia species, MIMOSACEAE ),
  • Banana Fruit ( Musa acuminata, MUSACEAE ),
  • Passionfruit ( Passiflora edulis, PASSIFLORACEAE ),
  • Primrose ( Primula, PRIMULACEAE ),
  • Roses ( Rosa odorata, ROSACEAE ),
  • Gardenia ( Gardenia jasminoides, RUBIACEAE ),
  • Willow ( Salix, SALICACEAE ),
  • Lantana ( Lantana camara, VERBENACEAE ).

    In plantation forests, they are a pest on :

  • Monterey Pine ( Pinus radiata, PINACEAE ).

    In the wild they feed on plants such as:

  • Coral Pea ( Hardenbergia species, FABACEAE ),
  • Wattles ( Acacia species, MIMOSACEAE ),
  • Bottlebrush ( Callistemon species, MYRTACEAE ),
  • Ferns ( POLYPODIOPHYTA ), and
  • Spider Flowers ( Grevillea species, PROTEACEAE ).

    The males grow to a length of about 2 cms. The females grow to about 3 cms.

    They pupate amongst the leaves of the foodplant in a sparse cocoon that they decorate with hairs from their larval skin, making these cocoons likely to cause urticaria too. The adults emerge after a few days.

    The female adult is dull brown with intersegmental fringes of pale hairs. She is fat and flightless. She stays beside her cocoon emitting a pheromone to attract males. She lays eggs on and around her cocoon after fertilisation. She has a length of about 1 cm.

    The male has light or dark brown patterned forewings, and yellow hind wings with a broad black margin. He has a wing span of about 2 cms.


    Perhaps because the females being flightless, the newly hatched Caterpillars have a special way of dispersing by spinning threads of silk which are caught in the wind ("ballooning"). So the species is found over most of Australia, including

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

    They seem to have ballooned their way across the Tasman because the species appeared in

  • New Zealand.

    So far this species has not spread beyond Australasia, although related and similar species occur in America.

    The sex pheromone components of this species has been determined by an international research team of Dr. Gerhard Gries (Simon Fraser Univ., Burnaby, B.C., Canada), Dr. John Clearwater (Clearwater Research & Consulting, Auckland, NZ) and Dr. Paul W. Schaefer (U.S. Dept. of Agric., Beneficial Insect Introd. Lab., Newark, USA). In December 2003, John Clearwater and Paul Schaefer completed the final field confirmation trapping in Campbelltown, NSW, using a completely synthetic lure, which proved to be very effective at attracting the males into traps. Therefore, there is now a powerful field sampling tool for population assessment, clarification of distribution or habitat preference, or behavior studies. This research was supported in part by Global Forest, an international research institute based in Banff, Alberta, Canada.

    Control of the species is being attempted using:

  • extracts from the bacterium Bacillus thuringiensis
  • the release of irradiated (infertile) males, and
  • natural fly and wasp predators.
