Cool, mostly overcast morning, clearing before noon and warming to 70’s. During a 2.4 mile walk mainly in natural areas of riparian park, I counted 210 Pipevine Swallowtails, 1 Western Tiger Swallowtails, 1 Cabbage White, 3 Mournful Duskywing, and 3 Silvery Blue. Pipevines started flying early in walk. Others seen mostly toward the end as it warmed up. the pipevines were mostly in continuous flight till toward the end of the walk. Then I found them nectaring on redbud, fiddleneck, and vetch.

Hudson Highlands State Park, north of Cold Spring
Putnam County, NY

cloudy start, then partly sunny, brighter at times in p.m. hours, high in mid-60’s F. - the butterflies seen were almost all during the sunny intervals. No photos of these, although attempted along the trail; not many nectar sources easily seen, yet. Also observed and photographed was a tiger beetle, Cicindela limbalis. Most of the Cabbage Whites were seen in the town. The 1 Falcate Orangetip was male and would not stop patrolling on a steep rocky slope! Trail climbed to summit of Mt. Taurus, where at least ‘commas & cloaks” were hilltopping and cavorting; 1 azure also near there.
