Meet Monarchs: ‘Endangered’ traveller butterflies that survive on poisonous milkweed
Monarch butterflies are facing an endangered status due to habitat loss, climate change, and pesticide use. The article highlights their unique reliance on milkweed, which provides both a nursery for their larvae and a chemical defense mechanism against predators.
Why it matters
Understanding the monarch's lifecycle and environmental threats is crucial for conservation efforts aimed at preserving biodiversity and migratory species.
Picture this: Every autumn, one of nature’s most extraordinary journeys begins with a creature weighing less than even a gram! Millions of monarch butterflies, light as a feather, take to the skies across North America, travelling thousands of miles from their summer breeding grounds towards overwintering forests in Mexico. Some eastern monarchs can even travel up to 3,000 miles (about 4,800 km) during the migration. Quite an astonishing distance for an insect whose wings can fit comfortably across the palm of a hand!Then again, Monarch butterflies are famous for this epic migration, but lately, their story is tinged with real concern. In 2022, the International Union for Conservation of Nature (IUCN) declared the migratory monarch butterfly Endangered. Habitat loss, pesticides, climate change, and ruined wintering forests have slashed their numbers. Those in the west have been hit especially hard.
