Description
at Bangalore
In shape, colour, and markings, very closely resembles Euploea core. Males, however, can be distinguished at once by the presence of two brands instead of a single one on the fore wing. Of the females Lionel de Nicéville says, females of E. coreta can be separated from the females of E. core by the following points: "First by the outline of the fore wing being more entire ; in core it is slightly but perceptibly scalloped- Second, by the underside of the fore wing 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 fore wing in the male are faintly but quite perceptibly to be traced in the female in the same position."[2]
