Clover Looper moth, Caenurgina crassiuscula
Calvert Vaux Park, Brooklyn, NY, 2007-09-20
Calvert Vaux Park (nee Dreier-Offerman) is one of the little-known jewels in Brooklyn. Although small, it has one of the most diverse batches of fauna over the year anywhere in Kings County. Sadly it’s going to be “improved” in the near future with astroturf and various other items designed to make it a “destination park”.
Buck Moth, Hemileuca maia
Metairie, Louisiana
Not a lot of moths up here in the cold Northeast right now (aside from one that flitted through my office at school a couple of weeks ago) but my parents found this one on their screen door in the somewhat warmer Southeast.
Great Golden Digger Wasp, Sphex ichneumoneus
Brooklyn Botanic Garden, 2007-08-18
Let’s finish wasp week with the Great Golden Digger Wasp, one of the larger and more impressive local NYC wasps (though sadly not one of my more impressive photographs. I am looking into improving my camera equipment.) This is actually a very widespread wasp across North America, and is commonly seen in gardens and parks.
The Great Golden Digger is a solitary (non-social) wasp that lays its eggs in burrows in the earth. It’s not very aggressive, but like most wasps will sting if you try to handle it. Adults feed on nectar but prey on other insects to provide food for their young, especially grasshoppers, katydids, and crickets. Thus like many other wasps they’re quite beneficial to gardeners and farmers, and should be left alone when encountered. Don’t bother them and they won’t bother you.

Northern Paper Wasp, Polistes fuscatus
Floyd Bennett Field, Brooklyn, 2007-09-23
Much less aggressive and problematic than the invasive European cousins from Day 4. Nonetheless getting too close to a nest would be an incredibly stupid thing to do. Like most social wasps they will defend their nests if disturbed. Otherwise they leave humans well enough alone.

Bald-faced Hornet, Dolichovespula maculata
Brooklyn Botanic Garden, 2007-08-18
Not really a hornet at all, this species is more closely related to yellowjackets. Like yellowjackets, they are omnivorous and both collect pollen and eat insects, even other wasps.
Although they have a reasonably distinctive appearance in the field, bald-faced hornets are most easily recognized by the large, paper nests they construct in trees. Sometimes these are easier to find when the leaves fall off the trees, but this one has been visible in the Brooklyn Botanical Gardens for months now.

Pipe Organ Mud Dauber, Trypoxylon politum
Brooklyn Botanic Garden, 2007-
Mud Daubers are more recognized by their nests than the wasps themselves. Above we have the nest of the aptly named “Pipe Organ” Mud Dauber. The adults are plain black and relatively non-descript for a wasp. As usually goes along with such non-descriptness, the Pipe Organ Mud Dauber is relatively harmless compared to other wasps such as yellowjackets. They avoid humans, and won’t sting unless seriously provoked (e.g. by catching one in your hand). They will build nests on human habitations. (I found this one outside the men’s room at the Brooklyn Botanic Gardens.) However aside from the aesthetic issues of having mud pipes on your walls, there’s little reason to remove them.
