Red-spotted Purple

Most of our dark, largish butterflies in this area turn out to be swallowtails (black morph Eastern Tiger Swallowtail, Black Swallowtail, Spicebush Swallowtail), but here's the most commonly seen exception, the Red-Spotted Purple.

You could quibble about the name. When I look at them I initially notice the black, then with a better look I'll detect some blue, and after that I'll notice some orange spots. (I suppose calling it the Orange-spotted Black-and-blue might suggest an insect with bruises in the aftermath of an injury.)

This is another example of the name being for a subspecies, not a species. The species name is Red-Spotted Admiral, which comprises both the Red-spotted Purple and the White Admiral. (Looking at the 2 subspecies, you'd probably think you were looking at 2 different species since they look fairly different.)

It's possible that the Red-spotted Purple has evolved to look similar to a poisonous swallowtail that I haven't seen but which is potentially in my area, the Pipevine Swallowtail.

I'm pretty sure I've seen several of these guys this season, but getting pictures of them has been a challenge. As butterflies that lean more towards drinking tree sap or the juice from rotting fruit than nectaring on flowers, I'm rarely going to catch them mid-meal and thus stationary.

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
