Jalmenus daemeli

This Caterpillar is initially green with a black pattern, but later turns brown with a white pattern. The head is black, and there are raised areas on the first and last segments. The Caterpillar is attended by the black ants :

  • Iridomyrmex rufoniger ( DOLICHODERINAE ).

    We have found it in Bundaberg feeding on the foliage of

  • Black Wattle ( Acacia leiocalyx, MIMOSACEAE ).

    but it may be found on almost any species of:

  • Wattle ( Acacia, MIMOSACEAE ), as well as
  • Silver-leaved Ironbark ( Eucalyptus melanophloia, MYRTACEAE ), and
  • Scrub Boonaree ( Heterodendrum diversifolium, SAPINDACEAE ).

    The Caterpillar grows to a length of about 1 cm.

    Jalmenus daemeli

    It pupates under a leaf of the food plant, the pupa being initially green with brown markings, and later brown. The pupa also attracts the same ants. The pupa also had a length of about 1 cm.

    Jalmenus daemeli

    The adult has metallic blue wing upper surfaces, with two eye-spots by a little tail on each hind wing, and a short black bar on each forewing.

    The under-surface has a pattern of fawn and brown, and also has a pair of eye-spots by the tail on each hind wing. The butterfly has a wingspan of about 2 cms.

    The eggs are laid in small clusters on a branch of a young plant. The eggs are white round and flattened, with a diameter of about 0.6 mm.

    The species is found mainly in the coastal areas of

  • southern Queensland.
