June is National Pollinator Month, so we wanted to shine a spotlight on the fascinating monarch butterfly! 🦋
Monarch butterflies are known for their iconic orange and black markings, but they are equally impressive for their ability to travel up to 3,000 miles between their summer breeding grounds and overwintering sites. Some monarch populations, however, are non-migratory and breed year-round in parts of central and south Florida, the Gulf Coast, and California.
To further add to their fascinating traits, monarchs start life as eggs laid on milkweed plants, which hatch after two to five days. The newly emerged caterpillars often consume their eggshell before moving on to an exclusive diet of milkweed. Over the next two weeks, monarch caterpillars progress through five instars (growth stages between molts) as they grow.
Once fully grown, the caterpillar spins a silk pad and hangs upside down in a "J" shape by its hind prolegs. Shedding its skin one final time, it forms a chrysalis. About one to two weeks later, an adult butterfly emerges, expands its wings, and the life cycle begins all over again!
Happy 🦋
