In the morning just before the rain we went to check if the second brood of Bronze Coppers are out. Spoiler alert: we did not see any but the third brood should be out soon.

1:15-4:10 warm with sun and clouds. So cool to see the gray commas which were a first for me!! All 3 are pictured - amazing how vibrant they are on the dorsal side. First time I've seen more than one snout, and first time seeing a least skipper out on gravel. Note the nice rainbow scales on the back of the peck's skipper. Also another high species count at 20.

4:00 to 5:00 pm. Sunny and breezy. Butterfly numbers and diversity here have been abysmal this year and last year. I wonder if all of the land remediation and construction in adjacent areas in the past few years has had an effect.

10:45 to 2:00. Mixed sun & clouds with low humidity and temps upper 60s to mid-70s. Visited several areas on the west side of the park. Swallowtails not very numerous despite large stands of Monarda. Saw no Silver-spotted Skippers. Perhaps the next week or two will yield larger numbers.

10:00-4:45. Mostly cloudy. Humid, in the 70s. We were having a very good day and that was before a Harvester decided to make friends with us! As we were walking along, a butterfly began fluttering all around us, particularly round and round our heads. Couldn't figure out what it was, and then it landed on my hand - a Harvester! It continued to land on one of us and then the other, obviously enjoying our company (and our sweat)! After being photographed and oohed and aahed over for about twenty minutes, our little buddy finally flew off. One of those magical moments, and great way to see a "lifer!" Many plants in full bloom, including Monarda, Knapweed and Joe Pye Weed. Also New York Ironweed and Goldenrods beginning to flower. Two Duskywing and fifteen dark Swallowtail flybys. One cooperative Cicada.

10:40 to 12:10. 73-82º and mostly sunny. Walked the perimeter of the fields between Goodale Road and the office. Could have covered more but ZuZu protested. Came close to sweeping the resident swallowtails but try as we might we could not find a Black. This means of course that we did find a Pipevine - and what a beauty!

Giant ST's were engaged in courtship with the male hovering several inches behind the nectaring female. They finally flew together up high into one of our hickory trees, out of sight. The Pipevine was the first I've seen in my garden in several years - a very nice surprise.

Random observations throughout the day. Very fresh Red Admiral and Hackberry Emperor. I photographed the emperor while it was on my pants. The 17 species we saw in the yard this day was the best we have done this year—a far cry from the 20-25 daily counts we routinely achieved in late July and early August up through 2018.

First Tawny I've recorded in my yard.

Not certain about my duskywing ID, so please correct if I'm wrong!

The Monarch Chrysalis had just pupated so was still wriggling around a bit. You can clearly see the wings, legs, eyes and attennae at this stage

Activity has been fluctuating with some busy days and then others with only one or two individuals. Far better than this past spring. I am happy to see there has been some breeding. I was hoping I could add a Swallowtail to the list. I was unsuccessful in doing so. Maybe next week.
Caterpillar sightings:
2 Black Swallowtails on Queen Anne's Lace, various instars of Monarchs sharing the Common Milkweed with Milkweed Tussock Moths, 1 Pearl Crescent on Aster, a late instar Silver-spotted Skipper on Black Locust along with a few tiny flaps seen in some Hog Peanut, and 3 Red-spotted Purple (based on my observation that they are feeding during the day and Viceroy typically do not) on a potted sapling Willow.

While walking the property I saw a Summer Azure on Goldenrod. When I passed later, I saw a Summer Azure on the same Goldenrod. I am guessing it was deceased. The Wild Indigo Duskywing was ovipositing on Crown Vetch.

Pleasant Plains Rd, Trailhead parking lot on Long Hill Rd, parking lots on N side of refuge. abundant Joe-Pye weed, Ironweed, Purple loosestrife on Pleasant Plains Rd but relatively few butterflies. Most of the Monarchs seemed to be females looking for milkweed. Broad-wings at the lot on Long Hill Rd. Note the HW of the Appalachian Brown; the basal line has an inwardly-directed "tooth".

Am missing eggs and little cats this year- only find them when they are unmistakably large. I still have blooming milk weed because I water it, unlike the truly wild plants that dry out when it does not rain.
