The Caterpillars feed inside the seeds in the fruits of the trees :

  • Songga Tree ( Strychnos lucida, LOGANIACEAE ), and
  • Strychnine Scrambler ( Strychnos minor, LOGANIACEAE ).

    The Caterpillars pupate within the emptied seed case, attaching it to the tree so that it does not fall to the ground. The pupa is smooth and pinkish-brown with dark markings.

    The adult butterflies on top are iridescent blue with a wide black margin. The females have an additional white patch on each forewing. Underneath: both sexes are pale brown with a darker brown margin and subterminal arc darker blobs on each wing. The hind wings each have a lobe and a tail by the tornus, adjacent to which is a black spot. The females are larger: the males have a wingspan of about 3 cms. The females have a wingspan of about 4 cms.

    The eggs are white, round and flattened, with a diameter of about 1 mm. They are laid singly on fruits of the foodplant.

    This species is found in the north of Queensland, and occurs widely throughout the Cape York Peninsula south to Undara Crater. The riparian thickets along the lagoon and stream edges include dense stands of Strychnos lucida. The fruits on these trees support a large population of the butterfly.
