Sleepy Orange

Here's a Sleepy Orange butterfly. This butterfly is one of the sulphurs, and in my area is probably the 4th most common butterfly in the subfamily. It's one of two butterflies that are easily confused with the Orange Sulphur due to similar coloring; the Sleepy Orange is probably only slightly more vibrant and has different markings. By comparison, the Clouded Sulphur is slightly less vibrant than the Orange Sulphur but with virtually identical markings. (The Clouded and the Orange Sulphurs can hybridize. As far as I know, the Sleepy Orange cannot hybridize with either of the others.)

We also have Cloudless Sulphurs in my area, but they're less likely to be mistaken for the others because they're both larger and paler. After these 4, I haven't encountered any other sulphurs around here, but these 4 species combine to make mostly-yellow butterflies a very common sight.

Up until about 3 years ago the Sleepy Orange hadn't been found in Somerset County, but the last couple of years they've become semi-common at Duke Farms even though they're awfully hard to find elsewhere in the county. The theory is that the Wild Senna that Duke Farms took pains to restore to the property has enabled the Sleepy Orange to carve out a home there.

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

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
