It's easy to overlook insects, but they play a crucial role in ecology. Over 75% of Earth's flowering plants rely on insects to reproduce. Learn more about pollinators at this National Park Service subject site. Insects are also an essential part of most food webs. Without insects, it would be very difficult for humans to survive!
Although all insects are important, we want to give a special mention to the Monarch Butterfly. Every September, Gateway Arch National Park and the City of St. Louis commemorate National Public Lands Day by with a special event celebrating monarch butterflies. The Great MonArch Migration Event brings attention and awareness to the beautiful monarchs, and helps visitors learn steps they can take to help monarchs have a bright future.
