This Caterpillar was deliberately introduced and released into Australia from its native Mexico in 1914 in a failed attempt to control the exotic weed:

  • Lantana ( Lantana camara, VERBENACEAE ).

    Similar attempts were successful in

  • Fiji, and
  • Hawaii.

    The food-plants also include:

  • Lemon Verbena ( Lippia alba , VERBENACEAE ), and
  • Mexican Oregano ( Lippia graveolens , VERBENACEAE ).

    The butterflies hve brown forewings, with the males having a large dark spot in each forewing cell. The hindwings are blue, each with two dark spots on the margin near the tornus.

    The undersides are a mottled brown, with pale areas by the tips, and two dark spots on the hind margin of each forewing. The butterflies have a wing span of about 2 cm.

    The eggs are laid singly on flowers of food plants. The caterpillars feed on the flowers and fruits of the food plants.

    The species occurs widely in the Americas, including

  • Argentina,
  • Jamaica,
  • Mexico, and
  • U.S.A..

    The species failed to establish in Australia, and probably no longer occurs here.
