This species can be found in a wide range of
habitats including secondary forest, savannah, thorn scrub,
farmland, parks and gardens, at altitudes between sea level and
The larval foodplant is

Both sexes fly rapidly along forest edge
habitats, pausing for a moment here and there to nectar at flowers.
