Molts
You should be seeing the shed exoskeleton’s of Atlantic Horseshoe Crabs on our beaches now. Note how they are hollow right down to the smallest joint. As arthropods, Horseshoes must molt to grow larger: they do it about half a dozen times during their first year and then some 18 more times after that before…

Corner Pocket
A fairly representative New York City tree pit. “Pit” is definitely the word here. The hard-pan — calling this sterile-looking misery “soil” would be an insult — looks like something you’d find in a draught-ravaged desert. And you can imagine the gallons of poisonous dog piss that have been poured in over the years. It’s…

Blue Wings To Die For
The Great Black Wasp (Sphex pensylvanicus) is a katydid and grasshopper hunter. As with the spider hunters and others I’ve been detailing this summer, the prey provisions the nests of their young. In between wrestling paralyzed katydids to the nest, these wasps sup on nectar. Like most solitary wasps, this generation never see their progeny…

Brooklyn Sunset
I like to think of these as a herd of giraffe, heading towards the last watering hole of the day across the harbor in New Jersey.Brooklyn Bridge Park, where all these pictures were taken tonight, is scarce on mammals. This rat, a creature of the docks if there ever was one, was larger than it…

Twelve Spotted
The Twelve-spotted skimmer (Libellula pulchella) is one of the easiest dragonflies to identify. You can even tell from the shadow. This is the female — the males have white patches between the dark spots.

Short-horned Long-horn
Genus Melissodes, a long-horned bee. The females don’t have the really long horns (actually they are antennae). Note the hairy legs thick with pollen.A solitary bee. There are more than a dozen species in New York. Sunflowers are one of their main food sources.

Wasps
It is the season of wasps. Seen on a walk through Prospect Park this week:The very elegant Isodontia elegans, one of the grass-carrying wasps, and evidently a species without a common name. The grass they clip and carry is used to line their nests, which are made in pre-existing cavities. They eat pollen themselves and…

Hymenoptera
Last weekend, I visited the Flatbush Gardener’s garden. The highlight was the mountain mint, alive with pollinators. I mean, jumping with pollinators: several species of bees, wasps, flies, and butterflies going at it. Here are a couple of the highlights: Great Golden Digger Wasp, Sphex ichneumoneus.One of the grass-carrying wasps of genus Isodontia. Cuckoo bee,…

Yes, we have egrets
The larger Great Egret (Ardea alba) and the smaller Snowy Egret (Egretta thula) are sometimes found side-by side, making the size differential between them easy to see at a distance. For more detailed observation, especially in flight, the Great has a yellow bill and black feet, the Snowy a black bill and yellow feet. Note…

Tachinid
Most flies get very little respect. Perhaps it’s their hairy rumps? Or maybe it’s that their larvae are parasitic on caterpillars? But Tachinidae flies are also pollinators, and so the plants approve.
