In the Life of Western Butterflies

Many of us know the butterfly life cycle—egg, caterpillar, chrysalis, adult. But how does this life cycle work in the hot Mojave or Sonoran deserts? What are butterflies in isolated springs across the West eating as caterpillars? How do they survive the winter in the Cascade Mountains? And how are these butterflies responding to habitat loss, pesticide exposure, and the changing climate we all find ourselves in? The western United States contains hundreds of butterfly species, found in habitats ranging from hot, arid deserts to the peaks of the High Sierras. While some of these butterflies are widespread and can (luckily) be found in gardens, parks and natural areas across the West, others are much more localized. All of these species have amazing strategies to survive and thrive in what can be some of the most hostile climates in the United States. And many of them are facing threats new and old to their populations and habitats. Join Kevin Burls, Endangered Species Conservation Biologist, as he starts with an overview of butterfly diversity in the West and then highlights some of the amazing strategies that have allowed them to colonize deserts, grasslands, and mountains. Kevin will also discuss the threats these butterflies face, and how we can all protect them and their habitats. ... Cover Photo: Sara Morris
