The Common Crow Butterfly (Euploea corinna) is one of the most frequently-encountered butterflies in the northern parts of Australia. It is very dark brown in colour, appearing almost black, with rows of white spots towards the edge of the wings. Due to its toxic nature (which arise due to the host plants of this butterfly), ingesting a single individual may be enough to induce vomiting in birds – a strong disincentive to eating!
The Pale Triangle Butterfly (Graphium eurypylus) is a large, Swallowtail butterfly that can be found in coastal regions of Queensland, the Northern Territory and far north Western Australia. They have a wingspan of around 6cm and belong to the Tribe Leptocircini that includes the Kites, Jays, Swordtails and Dragontail butterflies.
The Varied Eggfly Butterfly (Hypolimnas bolina) is a large butterfly from Family Nymphalidae that can be found in coastal and near-coastal regions of northern Australia. They generally have a wingspan for between 7cm and 9cm, though this can vary seasonally.
