The adults can be found feeding on a variety of flowers.
Idea is a mental image, form or appearance. Leuco is white.
The Giant Wood Nymphs are primarily found in mangrove swamps and the surrounding areas.
The adults spend the majority of their time flying throughout the forest canopy. They can also be found in surrounding areas visiting flowers. Eggs are laid singly on the host vines growing through the canopy. The larvae feed on the vines until they pupate which is also done in the forest canopy.
There are multiple generations each year which makes it possible to find adults flying throughout the year.
Idea is a close relative of the Monarch (Danaus plexippus). One trait they both share is that their larvae feed on toxic plants which in turn makes the larvae and adult butterflies distasteful to predators. Idea leuconoe has many common names. Some of the widely used ones are: Giant Tree Nymph, Paper Kite and Rice Paper Butterfly.
