THOMPSON, PA — Naturalist David Trently will lead a nature walk at Florence Shelly Preserve to discover and identify butterflies on Sunday, August 5 at 2 p.m. He will lead participants through the diverse 400-acre protected nature preserve to find butterflies in some of their preferred habitats: fields, woods, and wetlands. Among the species that might be spotted are the Northern Pearly-eye, yellow sulphurs (named because their yellow color resembles that of the mineral), fritillaries (which, unlike most butterflies, have no claws on their front legs) and skippers, named after their quick, darting flight habits. There is a chance, too, of encountering the small, rarer copper butterfly. Bring your binoculars for a closer look at your discoveries, and a camera as well.

Trently leads and plans birding walks for the Partnership for International Birding. He lives in Olyphant, PA.

Meet at the preserve parking lot one mile north of Thompson on Route 171, opposite Stack Road. The walk will last about two hours. It is free and no reservations are necessary. Participants will be asked to sign a release form. Call 570/727-3362.
