10:20 AM - noon. Hazy, humid, and 86 degrees. Most butterflies on Mountain-mint, between the Stahl parking lot and areas east and west of the silos. Few butterflies in the big Stahl fields or the field west of the River Road Park gravel lot. There is a little Monarda there but nothing nectaring on it. Only a single grass-skipper.

Whittingham WMA, Fredon Twp.

1:50-2:45. 87-90°. We checked the spot where another observer told us he recently had 50+ Com. Checkered-Skippers (at end of the grassy lane that leads east from the Whittingham office). We found them only on and near their White Clover nectar source. They are likely using Velvetleaf as a host plant.

Horseshoe Bend Park, Kingwood Twp
Hunterdon County, NJ

9:45 AM - 1:30 PM. Sun and Clouds, 90 degrees. Most butterflies seen in the southern part of the park, near the parking lot at the end of the road and in the lower of the two fields; we barely covered a quarter of the latter. Most action on the abundant Mountain-mint. Junipers an actual count, not an estimate, although we are sure there were many more. Fewer butterflies at the dog park, mainly sulfurs and swallowtails, and one nice Checkered-skipper at the gate. Dearth of grass-skippers. We found no anglewings, likely because we spent most of our time in the fields.

Observations made between 9:30 and 3:30. Gray Comma was a no show until after 2 p.m. Both were puddling. Likely males. Juniper Hairstreaks were actively nectaring on what appeared to be narrow leaved mountain mint, a few on common yarrow, and one on Wild Bergamot. One E.tiger was a dark form female. Spent very little time in the dog park field as Bobolinks were becoming agitated.
