The subspecies of Euploea sylvester are-[1][2]
In shape, colour, and markings, it very closely resemblesEuploea core. Males, however, can be distinguished at once by the presence of two brands instead of a single one on the forewing. Of the femalesLionel de Nicéville says, females ofE. coreta can be separated from the females ofE. core by the following points: "First by the outline of the forewing being more entire; incore it is slightly but perceptibly scalloped- Second, by the underside of the forewing having a complete series of six spots, one between each pair of nervules outside the cell; in core two of these spots, those above the discoidal nervules (veins 5 and 6), are always wanting. Third, the two brands on the interno-median area (interspace 1) of the forewing in the male are faintly but quite perceptibly to be traced in the female in the same position."[4][5]
The double-banded crow feeds on plants of the familiesApocynaceae (dogbanes and oleanders) includingParsonsia,Hoya, andCynanchum,[6]Asclepiadaceae (milkweeds) includingMarsdenia[7] andMoraceae (figs) includingFicus obliqua,Ficus microcarpa,Ficus racemosa,Gymnema sylvestre andIchnocarpus frutescens[8]
