With a tongue longer than its body and a sweet tooth for nectar, the Mexican long-tongued bat is one of the desert’s most important — and least seen — pollinators.
By night, they hover like hummingbirds, sipping from saguaro and agave blooms — and in doing so, they pollinate the plants that define the Southwest.
Their work helps ensure the future of tequila, wildflowers, and entire desert ecosystems.

Meet the cactus bee — a fuzzy, fast-moving specialist that’s only interested in desert blooms like saguaro and prickly pear.
They’re native. They’re solitary. And they’re vanishing.
Know them. Love them. Protect them.

Think butterflies are just pretty? Think again. They’re vital desert pollinators — and moths are even tougher, working night shifts in the heat. From monarchs to hummingbird moths, these wings keep wildflowers blooming.
Want to help? Plant milkweed, leave the porch light off, and skip the spray.
