Howell backyard.

The Monarch, a FOY sighting, was a quick fly by. It sailed through the yard, glanced briefly at the gaudy pink Rhododendron flowers, but did not stop to sample their nectar.

Summit Trail, Jenny Jump SF
Warren County, NJ

11:00 to 1:30. Sunny with temps in the 70s. With only six butterflies in 2.5 hours, this could have been a disappointing trip. But the two male Pipevine Swallowtails (one much larger and more aggressive than the other) saved the day. The larger one was very devoted to his sunny patch of flowering False Solomon's Seal and Downy Arrowwood and would repeatedly perch for a minute or two.

1:00pm-3:00pm. sunny, breezy, 77F, pipeline trail is quite muddy, especially in the lower portions.
Pepper and Salt Skipper was on the pipeline trail towards the bottom of the hill. However, it dove into the tall grass and I couldn't follow it with the grass moving back and forth in the breeze so didn't get a photo.
