The Discovery Center at Ridgefield is hosting a free butterfly program for all ages on Saturday, July 21 at 10 a.m. meeting in the Norwalk River parking area (the intersection of Route 7 and Simpaug Turnpike) in Ridgefield.

Local lepidopterist Victor DeMasi will lead this program and will share a collection of the fauna with a short discussion on butterfly ecology and conservation. The program will continue with a field walk in one of the most outstanding meadows in Connecticut to observe butterflies on the wing and present a few specimens for close examination, which will be released unharmed.

DeMasi is a research associate at the Yale Peabody Museum of Natural History. He has studied butterflies for the last 40 years in Connecticut and far away places such as the Amazon basin and Ethiopia.

Long pants, sturdy shoes and tick protection are advised. All ages are welcome, but children must be supervised. Reservations at 203-438-1063 or ridgefielddiscovery.org.
