Monarch Butterfly

Description
The Monarch Butterfly (Danaus plexippus) is one of the most recognized and studied butterflies in the world. Known for its striking orange-red wings with thick black veins and white-spotted black borders, the Monarch has a wingspan of 8.5 to 12 cm. This species is famous for its spectacular long-distance migration, traveling thousands of kilometers each year from North America to overwintering sites in central Mexico.

Life Cycle & Behavior

Like all butterflies, the Monarch undergoes complete metamorphosis: egg, larva (caterpillar), pupa (chrysalis), and adult. Females lay eggs singly on milkweed plants. The caterpillar hatches after 3–5 days and feeds exclusively on milkweed leaves, growing through five larval stages over about two weeks. The chrysalis stage lasts 10–14 days before the adult emerges. Summer adults typically live 2–6 weeks, while the migratory generation can survive up to 8 months. During migration, Monarchs can travel up to 160 km per day.

Host Plants & Habitat

• Caterpillar Host Plants: Milkweed species are the sole food source for Monarch larvae. Key species include Common Milkweed (Asclepias syriaca), Butterfly Weed (Asclepias tuberosa), and Swamp Milkweed (Asclepias incarnata).
• Adult Nectar Plants: Adults feed on nectar from a variety of flowers, including milkweed, asters (Aster spp.), coneflowers (Echinacea spp.), goldenrod (Solidago spp.), and lantana.
• Habitat: Monarchs inhabit open fields, meadows, prairies, roadsides, and gardens across North and Central America. They require both milkweed for breeding and nectar-rich flowers for feeding.

Identification Tips
