Natural Habitat
Fields, meadows, roadsides, and open areas where milkweed plants grow abundantly.
Diet & Feeding

Behavior Patterns
Active during the day and night. Adults and caterpillars sequester toxins from milkweeds to deter predators, and the bright coloration serves as aposematic warning.
Risks & Benefits
Benefits the ecosystem as a specialized pollinator of milkweed; poses no significant risk to humans, though caterpillars can sequester cardiac glycosides making them toxic to pets if ingested.
