Scientific Name: Papilio anactus

Other Common Names: Dainty Swallowtail, Small Citrus Butterfly

Species documented in by W.S. Macleay.


A small to medium size butterfly, mainly black and white with blue and red down the bottom quarter of the hindwing. Has yellow on the last half of the abdomen, and the buds of ‘tails’ on its hindwings.

Reported to be around September to late March.

P. Anactus is endemic to Australia, and is estimated to have evolved approximately 35 MYA (Zakharov et al, 2004). It is reported to be found in open woodlands, forests and gardens in QLD, but when found down south it is only found in gardens and could be described as an ‘urban butterfly’. Indeed, it has reached South Australia, as reported by Collier et al (2006). CSIRO report this species to be found in all but Western Australia and Tasmania (CSIRO, 2008).


Various species of Rutacea (Zakharov et al, 2004) and is also reportedly found on cultivated citrus such as lemons, limes and grapefruit.


The dingy swallowtail is currently (2008) classed in the Eleppone subgenus, although much debate over the classification of this insect continues, and is presently somewhere “between the subgenera Heraclides and Chilasa” (Zakharov et al, 2004). Only used to be found up north but its range was expanded down south by cultivated citrus.
