Dynamine postverta, the Four-spot sailor, is a butterfly in the family Nymphalidae. The habitat includes primary rainforests, humid deciduous woodlands, scrubby grassland and farmland. Adults primarily feed on nectar from small flowers but are also known to sip moisture and minerals from damp soil or decaying organic matter. Males frequently puddle in moist areas for essential nutrients.
