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…

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.

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,…

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.

Blue Dasher
The Blue Dasher dragonfly (Pachydiplax longipennis) is common around our ponds and lakes, especially if there’s lots of vegetation in the water. The males have a chalky blue abdomen, with black tip. The females have no blue at all. But they do have tell-tale paired yellow streaks along their abdomen.Dragonflies of this species will often…

Mud Cells
Two summers ago, a Black and Yellow Mud Dauber wasp built her nest in the Back 40 (inches). A new generation of these large, black-bodied wasps with yellow legs emerged in June of last year. This year I had one inside the house. Not here in Brooklyn, but at the family house in Massachusetts. This…

Two-Spotted in Brooklyn
One more species of lady beetle spotted in Brooklyn Bridge Park, on the catalpa trees, whose big leaves are sticky with aphid honeydew. This is the Two-Spotted lady beetle (Adalia bipunctata). There were several of them, so there must have been a recent pupation. This species is native to North American and Europe, making it…

Underneath the bathroom faucet: a small, pale spider.

Midge
This landed on my sunglasses recently. I’d never seen anything like it before. A single pair of wings meant it should be in the order Diptera, beyond that I give thanks to Bug Guide for narrowing it down to the non-biting midges of the tribe Chironomini. Note how the forelegs are unsually long, almost like…
