Mycalesis mineus

Dark-branded bushbrown

This tropical butterfly's caterpillars forcefully eject their frass pellets, a habit rarely seen outside skipper butterflies, and its wing pattern shifts between wet and dry seasons.

The Dark-branded bushbrown is a dark greyish brown satyrine with an obscure eyespot on the forewing, and males carry small dark scent brands on the forewing and hindwing overlaid with pale yellow hair tufts.

Adults fly with an erratic, jerky wingbeat through grassy clearings, gardens and riverbanks, feeding on rotting fruit rather than flowers, while caterpillars feed on carpet grass and other lowland grasses.
