Natural Habitat

Fields, meadows, roadsides, and open areas where milkweed plants grow abundantly.

Diet & Feeding

Adults feed on nectar from milkweed and other flowers; caterpillars feed exclusively on milkweed foliage.

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.
