Bees play a crucial role in U.S. agriculture as pollinators of many important crops, but they have experienced sharp declines in recent years. This interactive identification tool aims to help reduce this decline by facilitating identification of mites that may be found on bees and in their nests, and helping you distinguish harmless mites from those that might harm bees or their colonies. Bee Mite ID covers bee-associated mite genera from around the world, with an emphasis on those associated with important pollinators, including honey bees, mason bees, and bumble bees in temperate regions, and stingless bees and large carpenter bees in the tropics.
