I surveyed a little bit more of the area today. Nice, new Tiger Swallowtails. The front garden is full of Bergamot now and the skippers and hummingbird moths are absolutely loving it.

Most of the Milkweed has faded. Purple Cone Flowers, Gloriosa and Bee Balm starting to bloom.

Later in the evening I checked one of the flaps on the Hog Peanut and found a Silver-spotted Skipper caterpillar. Nearby on a Big-toothed Aspen Sapling I found a Brother Moth caterpillar and as I looked down on the same branch a mature Red-spotted Purple caterpillar in the same spot on found one in a previous year.

Observations from 11am-1:30pm. I began in Alexander's Meadow and on the western trail by the roped off path to the sugar shack came across a Northern Pearly-Eye. I could not find any entries in the sightings log for Northern Pearly-Eye for Somerset County, so I gather this is somewhat significant. I decided to try for a four Satyr day and headed back to Woodpecker Swamp for Appalachian Brown. This habitat is one we had picked out on the Great Swamp count as possibly holding Black Dash and Dion Skipper. I had visited this habitat a couple of times since the count with no luck, but today one head of Swamp Milkweed did have a Black Dash. I spent more time looking around that habitat and there seems to be a fairly healthy colony of Black Dash. I noted at least 8 individuals and given the small percentage of habitat I covered I bet there could be a few more. Mulberry Wing, which I also think is a notable Somerset County sighting was flying in this same area and nectaring on Buttonbush. I did not have a chance to photograph it. Lots of Wood-Nymphs today.

Thomas Edison National Historic Park Glenmont garden, West Orange
Essex County, NJ

An Essex County Master Gardener called the RU MG Helpline office this morning, with a photo of caterpillar on the cannas at the above mentioned garden. After looking up information it appears to be the larva of the Brazilian Skipper. There are at least 4 caterpillars and perhaps eggs at this cannas garden! They will do a complete check of their plants.

[Moderator]: Very unusual this far north. Upon checking with the gardeners, for more than 5 years the canna rhizomes have been dug up in the fall and replanted in the spring. No new cannas have been purchased during that time. Therefore, since Brazilian Skippers are strong fliers with a definite tendency to immigrate north, it's very possible that the caterpillars developed as a natural occurrence from eggs laid by a gravid female. Already this year two Brazilian Skippers have been seen in Cape May County and one in Cumberland County. Check your cannas!

1145 to 1300; sunny, 90 degrees, humidity 42%; very slight breeze. Given the peak condition of several acres of Milkweed, the farm's 36 acres of pasture and hay, as well as the large number of Oaks, Black Cherries, Locusts, and other host plants in the area, the paucity of butterflies is puzzling.

10:30am-3:30pm. Spent time in both the south and north section. The commas were seen in sunny gaps along the road in the wooded parts and along the rocky stream on the paved road in the southern section. I took a few horrible photos of the commas to confirm the identification. The Juniper Hairstreaks were very fresh, but stayed hidden within their namesake. A few unided duskywing species that never landed.
