The adult butterflies like to nectar at rotting fruit, but will also nectar at a variety of flowers.
This butterfly can be found in the rainforest and secondary forest. It is also found on banana plantations where it is considered an agricultural pest.
The female lays eggs in large clusters and the caterpillars feed gregariously at the edges of the hostplant leaves. The caterpillars can often be found resting along the leaf veins.
The Forest Giant Owl can be found in flight year-round.
Owl butterflies are crepuscular, meaning they are active at dawn and dusk.
