Guinea Paper Wasps

This summer I spotted some Guinea Paper Wasps. Based on the name, I thought the might be an invasive species from Guinea, or a namesake like Equitorial Guinea, Guinea-Bissau, Papua New Guinea, or Western New Guinea. But it turns out they are a native species, and it's surmised that the name came from this locality in Virginia or this other locality in Virginia. (They're more American than any Europeans, or any other humans.)

These wasps are considered paper wasps since they make nests by chewing up wood and other tough plant fibers to make their papery nests. (Paper wasp isn't a great taxonomic term though, since some of their close relatives make mud nests while some distantly related wasps make paper nests.)

They are eusocial insects, meaning they collectively share in the raising of young, a nest supports multiple generations, and the nest has a hierarchy of roles. Unlike some eusocial insects though, there's no apparent anatomic difference between the (all female) workers and the queen. And if a nest's queen should die, a senior work wasp will usually "grab the throne" and reign as the new queen.

Most of the native paper wasp species are considered to be fairly peaceful; certainly I wasn't attacked or obviously threatened when I was inside the structure taking these pictures. (By way of contrast, the invasive European Paper Wasp has a reputation for being as unfriendly as yellowjackets.) 

I suspect this first picture is a satellite nest, basically a new nest relatively close to the main nest. I'd imagine this is an early satellite nest, and (if all goes well) will be larger later in the summer. These nests are still affiliated with the main nest, and basically help colony survival if the main nest is attacked by parasites, predators, weather, etc.

This second picture is likely to be the main nest, though I suppose it could be subordinate to an even larger main nest in the area. (This seems unlikely though, since the wasps were using a roofed bird blind with no similar structures or large trees in the immediate vicinity.)

Tussock Moth Herd

Image
Some caterpillars are usually seen in large numbers (like Armyworm Moth caterpillars and Eastern Tent Caterpillars ), while most are more solitary. The Milkweed Tussock Moth caterpillars (more about them are here ) seem to be slightly social. I'll sometimes see them alone, but more often I'll see them in groups of 2-9 members. In the 1st picture below, you can see there is a clear size difference in some of these individuals. I'm almost certain the little one in the middle is in an earlier instar than the others (though they lack the colorful tufts of fuzz in their earliest instars).

Copper Underwing Caterpillar

Image
I believe this caterpillar to be a Copper Underwing [1]. At least the coloring and the dorsal hump (near the left end of the caterpillar) seem consistent with the Copper Underwing. These caterpillars are not what you'd consider picky eaters; my Caterpillars of Eastern North America describes their diet thusly: Many wooded plants including apple, basswood, blueberry, cherry chestnut, current, grape, greenbrier, hawthorn, hickory, lilac, maple, oak, poplar, raspberry, rhododendron, viburnum, Virginia creeper, and walnut. Wikipedia adds: Ash, privet, honeysuckle, rose, and service trees. That's a pretty wide range of trees and shrubs. One of the challenges of finding them is that they could be almost anywhere; the other challenges are: Their green coloring blends in pretty darned well with the average leaf. They have a habit of feeding underneath leaves, so they're probably not visible when looking down at their location. They have a tendency to move from leaf-to-leaf; if you

Eastern Pondhawks

Image
I'm going to try something different today with my Eastern Pondhawk pictures. I'm going to let ChatGPT do my blog today. (ChatGPT is an AI program that you can converse with in a pretty human way; an explanation of it is here .) Me:  Can you tell me something interesting about the Eastern Pondhawk? ChatGPT:  The Eastern Pondhawk (Erythemis simplicicollis) is a dragonfly species that is native to North America. It is a medium-sized dragonfly, with a wingspan of about 3 inches, and can be found in a variety of habitats, including wetlands, marshes, and ponds. One interesting characteristic of the Eastern Pondhawk is its mating behavior. Male Eastern Pondhawks are known for their territorial behavior and will defend their territory from other males. They will patrol their territory and will try to mate with any females that fly into their territory. Another interesting fact about the Eastern Pondhawk is that it is a fast flyer and is able to hover in midair. It is also an import
