Butterflies of Greenbrook and the Palisades
Each year, from early spring through autumn, visitors to Greenbrook can expect to see quite a variety of butterflies. Since 1975, 59 different species have been identified in the sanctuary. From red admiral caterpillars feeding on the leaves of false nettle to Zabulon skippers nectaring on hoary mountain mint to question marks “just passing through” in migration, butterflies can be observed in various activities and life stages.
Certainly not to be missed are the stunning monarchs passing along the Palisades, often in large numbers, on their miraculous fall migration to the high mountains of central Mexico.
Why not stop in at Greenbrook to see these fascinating butterflies? Who knows what you might find? Just this summer a pair of sachem skippers was observed right in the parking area—the first recorded observation of this species at Greenbrook.
