I've seen a Henry's Elfin only once before right near this spot. There may have been 2 but I never saw both together and it was in close proximity. Tons of coppers around! Beautiful view of a Red Admiral and the first time I've had a nice shot of the dorsal side. 2 other individuals that could have been Painted or American Ladies. Sunny and warm from about 3:25-5:00.

1330 to 1445; Sunny, breezy, temperature in the 60's. Some plants starting to bloom. Saw a Duskywing Sp. fly into one of the dry fields. Could not get close enough to it to determine species. Finally, some butterflies are starting to appear in this area.

2:30-3:30. Sunny, mid 60s. Many of the Pearl Crescents were nectaring on Common Cinquefoil. One of the Question Marks was feeding on sap oozing from a damaged willow tree branch. The sap was also attracting flies and what appeared to be a Yellowjacket. The Question Mark fended off interlopers by vigorously flicking its wings.

Seven observers, 9:30 AM to around noon. Started cool but warmed up some later but not really enough for good butterfly activity. American Coppers were much in evidence but we searched for Henry's Elfin without success. But a message arrived about Humpback whales off the beach, so we went to E-lot and there they were! So we spent a hour or so appreciating these larger creatures. Photos from Mike Newlon.

8:45 AM-12:15 PM. 52-58 F, breeze from the NW. Too cool for butterflies until around 11. Genhurst trails very muddy, bring rubber boots. Not a lot of nectar; Crescents on buttercup and dandelion, Whites on Garlic mustard and Wintercress. Two Whites found each other, went into a dogfight, spiraled upward until lost to sight even in binoculars.
