Everyone is invited to the meetings, which are free to all.

 The purpose of the club is to study butterflies and insects and to share that information at our meetings. Catch the enthusiasm and attend our lively club meetings. Most meetings include a lecture, discussion, and show-and-tell of books, bugs, host plants, or photos. Have a question on insects? These meetings are a place where you might just find an answer. Members and friends are invited to field trips in Lancaster County, Pennsylvania throughout the season. Learn what can be found in this area and meet other enthusiasts.

Members and friends are also welcome to participate in 3 butterfly walks, 2 of which are part of the North American Butterfly Association's nationwide Fourth of July Butterfly Count program which require a nominal participation fee by NABA. They are listed below.
