Leaderless Walk, 5 participants. Sunny, high temps in low 70's. [Moderators: This time of year at Sandy Hook Cabbage White is not the default white as it is in most of the rest of NJ as Checkered White (State Threatened) is sometimes reported from the Hook in September.]

Covered "The Garden " and "The Tennis Courts." I was there birding all morning. I saw the butterflies in the later part of the morning. [Moderators: First North Jersey sighting of Checkered White since 2017, and first Sandy Hook report since 2016. The most recent report from South Jersey (Cumberland Co.) was 2019. Good work, Grant!]

Van Ness WMA, Hamilton from Hughes Lane
Mercer County, NJ

This area is adjacent to Mercer County Park and the county has been putting in wildflowers - map in this article (https://www.tapinto.net/towns/hamilton-slash-robbinsville/sections/green/articles/mercer-county-park-wildflower-meadow-transformation-underway). There was quite a meadow at the west end of the lake /dam - knapweed, fleabane, blackeyed susan, goldenrod, vervain, etc. The Orange Sulphurs were entertaining and I found a Turtlehead plant on the Red Trail - nothing butterfly-like on it, but interesting. Found my own tiger moth caterpillar too.

The hawk counters at Raccoon Ridge had a great day with hawks and also kept track of passing Monarchs: "Monarch - 265!!!!!!! Incredible flight of Monarchs today".

C Wyluda

Mountain Lakes Park, Princeton
Mercer County, NJ

Did complete circuit including "pollinator meadow" but the only butterflies were found on copious white flowers (wood aster, fleabane, snakeroot) along the SW side of Red Trail. Goldenrod and thistles elsewhere but unused; much of park was noticeably dry.

Home garden & pollinator meadow, Fredon Twp.
Sussex County, NJ

Butterfly observations picked up after a very cool start to the day despite full sun.

At least 9 Monarchs were seen in our gardens and pollinator meadow in mid-afternoon. They were nectaring at New England Aster, Mistflower, 'Jeana" Phlox, Butterfly Bush, Purpletop Verbena, and Showy Goldenrod. An hour or so later despite full sun on most of the above flowers we were down to 4-5 Monarchs.

Eastern Comma was the 49th species of butterfly seen on our property this year.

While outlooking for Odes came across a nice number of Monarchs in the field near pond. Had six in sight at one time. I put ten as a count, probably were more.

C Wyluda

Pole Farm
Mercer County, NJ

circuit walk 5-6:30 pm. Nothing unusual but I did see multiple monarchs, pretty much all on thistles. Dog found a caterpillar which my guess is it's a Spilosoma virginica (Virginia tiger moth). [Kudos to C for giving her dog credit for finding the caterpillar which may very well be a late instar of a Virginia Tiger Moth.]

Sunny, low 80’s. Many Woolly Aphids in American Beech trees near the Orange Trail, 1 Harvester caterpillar found. All other sightings were in the field near the Dog Park. [Moderators: Harvesters have been riding high this year and last year but what will happen if most American Beech trees succumb to the various diseases as most Harvester colonies are associated with beech woolly aphids and not alder woolly aphids.]

10:45-2:30 including 1+ hour for lunch with my fellow NJ Fish & Wildlife employees at the annual fall bash. As a mere seasonal employee I was limited to 1 Hot dog (no chili topping!) and 1 burger but unlimited (I think) fruit salad.

10:00 - 1:30. Mostly sunny, 66-78 degrees. After finding zero Leonard's Skippers on 8/22 decided to take another look, which was certainly worthwhile. Most of the Leonard's were at the higher elevations and nectaring on Field Thistle. Nice numbers of Coppers, Blues, and Pearls, and an excellent count of Monarchs (for this year), which were nectaring on goldenrods and even White Snakeroot.

9:50AM - 1:10PM. Sun and clouds, 72-82 F. Covered just the areas around the parking lot. Most significant nectar sources came equipped with one or more large Praying Mantises. [Moderators: European and Chinese Mantises are (obviously) alien predators that voraciously prey on any insect (or even hummingbird) that they can catch. Given the alarming declines we are seeing in populations of butterflies and many other insects, this heavy predation by a creature that is not native to our ecosystem is certainly an unwelcome additional drain. One of your Moderators (SAW) routinely removes them “with extreme prejudice” and conducts search-and-destroy missions for egg masses in winter. These are NOT beneficial insects to be revered and protected, as so many of us were taught in childhood!]

2:20-5:40. Sunny and mid 80's. I walked the sand trails from the platform to the north end, L lot path, and area F road to the bay. Once again the Sachems were everywhere feeding on Camphorweed. Almost all of them were females. It was cool to see a Cloudless Sulphur all the way out on the north end on the beach. Also some nice looks at what I believe is an American Sand Wasp.

Sun and clouds, warm and humid. The very fresh female Fiery Skipper is our 48th yard species for 2023, and only the third one reported in North Jersey this year. Monarchs frequently nectar at goldenrods and asters in late summer and fall. But being large and heavy (for a butterfly) they prefer the larger and stouter species such as Showy Goldenrod (Solidago speciosa) and New England Aster (Aster novae-angliae), both of which are coming into bloom now in North Jersey. Most Silver-spotted Skippers look like they will soon cash in their chips, like the female here on our 'Jeana' Phlox.
