Did you know that milkweed is essential for the survival of monarch caterpillars? Monarchs rely on milkweed as the only food source for their caterpillars, making this plant a critical part of their life cycle.

Milkweed not only provides nourishment for these iconic pollinators but also offers protection. Monarch caterpillars ingest toxic compounds from milkweed, which make them less palatable to predators—a clever natural defense!

Sadly, habitat loss has reduced the availability of milkweed, threatening monarch populations. Planting native milkweed in gardens and green spaces helps create safe habitats for monarchs to lay their eggs and ensures caterpillars have the food they need to grow and eventually transform into butterflies.

Interested in supporting these beautiful pollinators? Consider planting milkweed in your yard and helping preserve their migration journey for future generations.

Meet the Coatis, curious creatures that call the desert home!
Found in Arizona’s desert scrub, woodlands, and riparian areas, these playful animals are relatives of raccoons. They are recognized by their long tails and social nature. During the day, they forage for insects, fruits, and small critters, using their strong claws for climbing and digging.
Keep an eye out—you might just spot one on your next visit to the Arboretum!
