Tiny yet mighty, hummingbirds are more than nectar lovers—they’re nature’s pest patrol. These aerial acrobats feast on whiteflies, gnats, and other insects, making them vital allies in your garden. By attracting them with feeders, you welcome not just beauty but powerful, feathered warriors that help maintain ecological balance. So, next time you spot one, remember: it’s not just sweet alone — it’s survival in motion. Anna's hummingbird feeding on whitefly from the family Aleyrodidae from Santa Clara in California.
