A subfamily of butterflies in the family Nymphalidae, known for their bright colors and slow, fluttering flight.
From Euploea (a genus of butterflies) + -inae (subfamily suffix). The genus name comes from Greek eu- (good) + pleo (to sail), suggesting beautiful flight.
Euploea butterflies are famous for their role in studying mimicry—unrelated butterfly species evolved identical warning patterns to fool predators, showing how evolution can lead different organisms to the exact same solution.
