The dog park was not very productive. But the unpaved entrance drive into the east section of the park was very busy with Questions Marks, Spicebush and Tiger swallowtails, Red-spotted Purples, and snouts. Seven of the 9 Gray Commas counted were on this driveway between the bridge and the utility line easement. A bit toasty today.

Mostly sunny, hot & humid all day, high 90 degrees. Nice to have our first yard count of 20+ species this year, but distressing that 14 of them were represented by only 1 individual. Our first Pipevine in a long time. New brood of Juniper Hairstreak out. One Snout was laying eggs on a Hackberry seedling.

I arrived at 11:30 am and stayed until 2:15 pm. It was hot (86-90º F) and sunny. Entering across from Blackwell Mills Road, I looped around the wooded area toward Federal City Road following the cut paths. Shortly after arriving, I observed a fly-by of a Cloudless sulphur and decided to count the butterflies seen today, as that is a very rare sighting for me in this area. The variety of butterflies out today was amazing for this part of the park! Not only that, but I observed 25 Monarchs (including three mating pairs) and a second Cloudless sulphur on this trip.

1200 to 1445; sunny, 80's. Several acres of pasture are devoted to Milkweed, in the hopes of helping Monarchs breed. An acre or so has been taken over by thistle which provides patches of nectar, which attract a variety of butterflies. Cloudless Sulphur is annual down her, but this is the earliest I have seen one. Most of my sightings are from August onwards.

used to wonder how people managed to "catch" butterflies ovipositing AND photograph the eggs, but now I know. Noticed that the eggs are left with unopened buds that are small and round themselves.

Female monarch was ovipositing in all my milkweed patches.

I am not totally certain on my id of the Hickory Hairstreak, but leaned towards that id owing to the very brownish color of both relative to Banded which always look more gray to me. Happy to be corrected if I'm wrong.

[moderator]: I'm not sure how reliable the ground color is in distinguishing Banded and Hickory Hairestreaks, but perhaps it's a good tie-breaker?
[moderator]: I'm not sure how reliable the ground color is in distinguishing Banded and Hickory Hairstreaks, but perhaps it's a good tie-breaker? The leading edge of the post-median band on the forewing of the left individual indicates Hickory. The right individual has all the field marks of a Hickory.
