This Caterpillar is green with a dark dorsal stripe bordered by yellow. It is covered in small white warts. It feeds on various types of Saltbush ( CHENOPODIACEAE ), for example :

  • Berry Saltbush ( Einadia hastata ),
  • Fat Hen ( Chenopodium album ),
  • Fleshy Saltbush ( Rhagodia crassifolia ),
  • Spiny Saltbush ( Rhagodia spinescens ),
  • Old Man Saltbush ( Atriplex nummularia ),
  • Slender Fruited Saltbush ( Atriplex leptocarpa ),
  • Bladder Saltbush ( Atriplex vesicaria ), and
  • Berry Saltbush ( Atriplex semibaccata ),

    as well as

  • Whitewood ( Atalaya hemiglauca, SAPINDACEAE ).

    The Caterpillar is inclined to leave the veins of the leaves uneaten, which is useful when hunting the beastie. It is usually attended by small black ants of various genera including :

  • Iridomyrmex species ( DOLICHODERINAE ),
  • Camponotus ceriseipes ( FORMICINAE ),
  • Monomorium rubriceps ( MYRMICINAE ), and
  • Myrmecia nigrocincta ( MYRMICINAE ).

  • Northern Territory,
  • New South Wales,
  • Victoria,
  • Tasmania, and
  • South Australia.

    as several races, including :

  • lavara (Couchman, 1954) on Tasmania, and
  • serpentata on the mainland.
