Dione vanillae
- Order & Family
- Lepidoptera: Nymphalidae
- Size
- 25-30 mm in length for the chrysalis; adult wingspan is 65-95 mm.
Natural Habitat
Open sunny areas such as gardens, fields, and parks, primarily across the southern United States into South America.
Diet & Feeding
The chrysalis phase does not eat. As caterpillars, they feed exclusively on Passionflower leaves (Passiflora). Adults drink nectar from various flowers.
Behavior Patterns
The chrysalis mimics a dried leaf to avoid predation. This is the non-motile pupal stage where the caterpillar undergoes metamorphosis to become a butterfly, typically lasting 10-20 days.
Risks & Benefits
Benefits the ecosystem as a primary pollinator in its adult butterfly form. It is generally harmless to humans, though caterpillars can defoliate passionflower vines.
