Montrouzier’s Ulysses Butterfly

The Montrouzier’s Ulysses Swallowtail Butterfly is native to New Caledonia. It prefers tropical rain forests. 

The adult butterfly sips nectar from flowers, whereas the caterpillar (the larvae stage) eats plant leaves. 

The female lays eggs on leaves. The eggs hatch into caterpillars after 3-6 days. The caterpillars eat leaves and after 12-22 days they undergo metamorphosis and change into pupae, which are casings. This stage is 8-22 days.

A casing is called a chrysalis. The adult butterfly emerges from the chrysalis. 

The adult butterfly lives for 4-6 days.
