The double-branded crow, Euploea sylvester, is a butterfly in the crow-and-tiger group (the danaids) of the brush-footed butterflies (Nymphalidae). It’s found in South Asia, Southeast Asia, and parts of Australia, with several regional forms. In Australia, the race pelor occurs.

Males can be told apart from similar species by the two brand marks on their forewings (instead of a single mark).

Females are described as having a more even forewing edge, a complete row of six spots on the underside of the forewing, and the two forewing brand marks in the inner area that are faint but can be seen.

Host plants (what caterpillars eat) include families and plants such as Apocynaceae (dogbanes and oleanders) like Parsonsia, Hoya, and Cynanchum; Asclepiadaceae (milkweeds) like Marsdenia; Moraceae (figs) including Ficus obliqua, Ficus microcarpa, and Ficus racemosa; as well as Gymnema sylvestre and Ichnocarpus frutescens.
