"A Container Garden for Butterflies" by members Margaret and Stuart Frentz. Before coming to Willow Valley, Margaret was an avid gardener, having turned what had been a plain grass yard in Birmingham into a variegated plot with a Japanese rock garden, native shrubbery, pollinator plants and herbs. Stuart’s photography hobby and sideline included an extensive collection of closeup photos of backyard birds. At SouthPointe, their focus shifted to plants and pollinators native to South-Central Pennsylvania. Margaret researched the types of host and nectar plants that would attract Monarchs, Black Swallowtails and other beneficial insects, and Stuart developed his macro and telephoto skills to begin recording the many visitors to their garden. They learned the hard way, starting virtually from scratch, making some mistakes along the way, but ultimately having a lot of success. In 2023, their first full year of butterfly gardening, they raised and released more than 40 Black Swallowtails and 20 Monarchs.

The regular meetings
of the Lancaster Butterfly &  Entomological Club are held on the first Monday of every month from April through October (except September when we meet on the second Monday).

Meeting Location:
Kinsey room on the second floor of the North Museum of Natural History & Science, at the corner of College Avenue and Buchanan Avenue, Lancaster, Pennsylvania.                Time: --- 7:00 to 9:00 P.M.

Everyone is invited to the meetings, which are free to all.
Please use the
Main entrance (which faces the intersection) and bring a friend.

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. 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 2 butterfly counts which are part of the North American Butterfly Association's Fourth of nationwide July Butterfly Count program which require a nominal participation fee by NABA. They are listed below.


The 2025 Butterfly sightings page is under construction but sightings are being accepted for 2025. Pages for past years can be found using the link below for 2024. A table of links to each year will be found there t the bottom of the page.

In 2023, their first full year of butterfly gardening, they raised and released more than 40 Black Swallowtails and 20 Monarchs. Among the challenges they faced were the Community’s restrictions on perennials (which meant using containers), and the difficulty of finding native pollinator plants grown free of insecticides and neonicotinoids.
