Air Bee and Bee

IMG_8777A local bee motel. There was a wasp checking in, to. This is a rather elaborate one, offering several possibilities for wood- and cavity- nesters. (But don’t forget the ground-nesters!)

The Xerces Society has some helpful hints on building your own to encourage pollinators.

Diggers

Scolia dubiaScolia dubiaDigger wasps (Scolia dubia) hide their lights under their dark blue-black wings. Scolia dubia“Blue-winged Wasp” is another common name for them.IMG_3774A bunch of these were looping over a strip of dirt on the edge of First Avenue at 41st, rather industrial ground for natural history, except for the feral cats and Paulownia and Ailanthus trees. But as is so often the case, the barrenness of the urban setting is deceiving. The wasps were hunting for grubs — of Japanese beetles, May and June bugs, etc. — beneath the surface, which they burrow after to sting and lay their eggs on. When not on the hunt for fresh grub meat for the next generation, they gather nectar for themselves, as this example (pics 2 & 3) in Green-Wood.

Sumer is icumen in

Sphecius speciosusI’ve heard a few Dog Day Cicadas (Tibicen) recently, at Jamaica Bay Wildlife Refuge and here in Cobble Hill, but it’s still early. In anticipation, the Cicada Killer Wasps (Sphecius speciosus) have begun to emerge. Males are generally seen first; they’re out to claim nesting territory.

I saw my first CKW of the summer on Tuesday. I assumed it was male since it looked so small. Wednesday before the monsoon I saw one in the same place. It really favors this wheel. If you look closely at the rear leg below, there seem to be spurs there at the joint, evidently a characteristic of females. Also, this view nicely shows the two pairs of wings, a defining characteristic of the Hymenoptera.

While scary to some people because of their size, these digger wasps are quite harmless to people.

Paper

Dolichovespula maculataAll that remains of that Bald-faced Hornet (Dolichovespula maculata) nest on the memorial I photographed in September. Dolichovespula maculataWhile examining the amazing paper the wasps make to cover their comb, I found something elsenesting between the layers. Oops, sorry about that!

BFH Nest Down

nestBald-faced hornets (Dolichovespula maculata) have been in the news recently. There seem to be a lot of their nests in Brooklyn: a bumper crop or just people noticing more of them? While some seem to think they are the Ebola of wasps, the wasps won’t bug you if you don’t bug them, or their nest. This magnificent specimen of wasp-paper was on the ground in Prospect. This year’s wasps are mostly done, except for mated queens, who stash themselves for the winter elsewhere.

O brave new world

That has such creatures in’t! These are all new discoveries for me, excepting the last, because there’s one thing the arthropods prove, and that’s ever-new discoveries.Acharia stimuleaThe aptly-named named Saddleback caterpillar (Acharia stimulea), about 2cm long. The adult moth is one of the fuzzy indistinguishable brown jobs, but this larval stage form is amazingly unique. The sting from these spines “may be the most potent of any North American caterpillar” says Wagner. The most elaborate caterpillars generally are giving you a warning. Spotted at the Charleston Cemetery, far western Staten Island, and untouched, although I wasn’t aware of the nasty sting at the time.Cisseps fulvicollisYellow-collared Scape Moth (Cisseps fulvicollis) seen in Green-Wood. A day-flyer, gathering nectar amid masses of wasps it vaguely mimics. The image in Peterson’s field guide shows an orange collar and Bugguide.net notes that the vast majority are orange-collared, so the common name is a little less than helpful. Robber FlyAnother wasp-like non-wasp. This is one of the robber flies in the family Aslidae. It hunts bees and wasps and was patrolling the path along the Marine Park Salt Marsh trail. It would fly low, land, and stare at me until I got too close, then fly forward to land again and stare back at me. Those whiskers would do a hipster proud. Eremnophila aureonotataMating Thread-waisted Wasps (Eremnophila aureonotata) at Mt Loretto. I’ve since seen a few solo of the species flying, trailing that long, long waist.Dolichovespula maculataBald-faced Hornet (Dolichovespula maculata) nest in Green-Wood. Their paper nests are usually hiding up in the trees, but recently I’ve seen pictures of them in the grass, and built around the supports of a basketball net.Dolichovespula maculataYes, they are at home. No, they are not taking any visitors.
