The Norwalk River Watershed Association (NRWA) invites people of all ages to a free butterfly walk, led by lepidopterist Victor DeMasi, in Redding on Saturday, Aug. 20, from 10 to noon.

DeMasi has been studying butterflies and moths in an area along the Norwalk River since 1977. During the walk, he will talk about area butterflies and moths and their food and habitats, share his collection, and teach people about the plants and trees Connecticut butterflies need to survive.

The butterfly walk will begin at 10 Simpaug Turnpike in Redding. Long pants, sturdy shoes and tick repellant is recommended.

The walk is sponsored by the NRWA, a not-for-profit membership organization focused on improving the water quality and fish and wildlife habitats of the 40,000-acre Norwalk River watershed, which includes the towns of Norwalk, Wilton, New Canaan, Weston, Redding and Ridgefield, Conn., and Lewisboro, N.Y.

The rain date for the butterfly walk is Sunday, Aug. 21.

Reservations: 203-448-0106 or victormonarch@yahoo.com.
