Butterflies
Big Morongo Canyon Preserve is home to at least 74 species of butterflies, with more likely to be found. The Preserve’s 31,000+ acres contain a wide variety of habitats – Sonoran and Mojave Desert ecosystems, riparian woodlands, former cultivated lands, Mojave yuccas, and pinyon, oak, and juniper woodlands. Its proximity to the higher San Bernardino and San Jacinto Mountains and to northwest Mexico adds potential for rare strays. Lorquin’s admiral, painted lady, great purple hairstreak, Becker’s white, and western tiger swallowtail are just a few of the varied and colorful species found along the reserve’s trails. The native plant and pollinator gardens near the preserve’s Education Center are good places to learn about some of Big Morongo’s lovely and diverse butterflies.
Mammals
The preserve is home to a number of mammals, including mule deer, desert bighorn sheep, raccoons, bobcats, coyotes, ground squirrels, kangaroo rats and other rodents. An occasional mountain lion and black bear have been sighted here as well. The availability of water brings the bighorn sheep and other animals into the canyon during the hot, dry summer months.
Arachnids
Tarantulas and scorpions reside in the preserve, along with many varieties of spiders. Tarantulas are completely harmless. Scorpions can produce a painful sting, but are rarely seen during the day. They are usually observed at night, using a UV light that makes them glow.
