Tiny titans run the world! Three quarters of the known animal species on planet Earth are insects, and Mercer area residents are invited to celebrate their impact on our lives at the Rutgers Master Gardeners of Mercer County's 21st Annual Insect Fest on Saturday, September 6. Fun, hands-on activities will teach attendees about the vital role of insects and how they create the biological foundation for all terrestrial ecosystems. The Fest will run from 11:00 AM to 2:00 PM at the Mercer Educational Gardens, 431A Federal City Road in Hopewell Township. Admission and on-site parking are free.
