Pulling “chestnuts” out of the etymological fire
The Chestnut Oaks, Quercus montana, are ripening in Prospect park. This species’ common name stems from the leaves, which are somewhat chestnut-like, although the acorn, over an inch long in this species, is all oak.The remains of a squirrel feast on what I believe is Yellow Buckeye, Aesculus flava, in the Vale. Included here because…

Skipper
One of the numerous small butterfly species called skippers in the family Hesperiidae. Many look quite similar to each other, so I gave this one to the Bugguide crew, and last I checked there was no response. I usually see them skipping about meadows and overgrown lawns; this one was on a butterfly bush in…

Summer Flounder
D’oh! Forgot to take my camera when we took Nora to the Maria Mitchell Aquarium. Next time. But in the meantime, on the porch of the MMA administrative building, next to the whale bone, I found this dessicated Summer Flounder (Paralichthys dentatus), classic example of a flatfish with both its eyes on the top side.…

Ailanthus Webworm
I was working my way up to taking a picture of the Ailanthus sapling that appeared this summer in a crack in the concrete in the Back 40. I was looking forward to a tree growing in Brooklyn, at least until the landlord saw it. But the Ailanthus Webworms got to it before I did.…

Only female adults will emerge from these in the late fall, and lay eggs (without mating) on leaf buds. These eggs over-winter, hatching in…

Life Cycles in Brooklyn Bridge Park
The rare Two-spotted lady beetles (Adalia bipunctata) I discovered in July are still active in Brooklyn Bridge Park. In fact:“Houston, we have coition.” Luckily, I didn’t learn about reproduction from Republicans, so I know that this kind of activity leads to:Lady beetle eggs. I assume Two-spotted, but don’t know for sure.A recently emerged adult, whose…

Drama in the corners
And in this corner, a click beetle, so named because they make a “click” when they flip up into the air (it helps them turn over should they find themselves belly-up) and a spider. The battle, such as it was, lasted for most of a day. I could hear the haunting click from a neighboring…

Lady Parts
Painted Lady butterflies (Vanessa cardui) are all over the city. Yesterday I counted a dozen at one flowery corner in Gowanus, and another dozen around a couple of butterfly bushes in Brooklyn Heights. This species is similar to the American Lady butterfly (Vanessa virginiensis), as you might expect for a genus-mate. Here’s an American Lady…

Great Blue Skimmer
For your August weekend, Libellula virbrans, spotted today in Brooklyn Bridge Park. A male. At 2.2 inches, this is one of our larger dragonflies, and it’s a great percher: this one returned to the same cattail leaf half-a-dozen times as I watched and photographed. More common in the southeastern swamps, but reaching up to Mass.…
