10am-12pm Butterfly Count
Join Audubon Mid-Atlantic as we conduct an annual butterfly count. With beautiful native flowers in full bloom, we'll be looking for the butterflies that call The Discovery Center home. Monarchs, Swallow-tails, Painted Ladies, etc. We'll take this morning to survey and find as many species as we can, talk about native plants, and discuss how you can bring these beautiful creatures into your own yard!

Butterfly guides and a limited number of butterfly nets are provided. Feel free to bring your own!
