Mountainside Park, Pequannock
Morris County, NJ

11:15 to 12:45. Sunny and clear with very little wind. Butterfly observations were casual in the course of a hike. Best surprise were the Cloudless Sulphurs. I saw 4 in the air at once and continued to see them much of the hike, but not sure if seeing the same individuals over and over. Was interesting to see an Orange Sulphur chasing a Cloudless, to give perspective on great size difference.

High Point SP, Wantage Twp.
Sussex County, NJ

Did our annual Leonard's Skipper survey at the shale barrens site that we discovered many years ago. The total of 39 was at least twice the previous high count. All were observed taking nectar from Spotted Knapweed (Centaurea maculosa) an alien, invasive, species from Europe which is well adapted to grow in dry, sunny, disturbed habitat. Will survey the only other known location in NJ (Yards Creek, Blairstown, Warren County) to support a double digit population this week to determine if this population is also higher this year.
