Bold Jumping Spider Gatekeeper

This Bold Jumping Spider was patrolling the gate that separates Willowwood Arboretum and Bamboo Brook. Unlike this older picture, you can't see the iridescent green chelicerae (kih-LIH-sih-ree) on this Bold Jumping Spider, though I think you can see a little green around the mouth [1]. They also (usually) have a white-to-orange spot on the back of their abdomen [2], though I'd probably consider this more of a gold or dark yellow spot myself.

Although the average person would probably classify these spiders as "small", it's probably 1 of our larger jumping spiders. Some of our fishing spiders, grass spiders, and orbweavers can be quite a bit bigger though. I suspect they're considered to be pretty common by jumping spider standards, though it's possible I just see them more because of their larger size.

Despite having "bold" in their name, most of the time these spiders seem frightened by me and my camera. I'm sure that by jumping spider standards, I'm stupendously large and thus potentially dangerous, so perhaps discretion is the better part of valor when they encounter humans.

This Bold Jumping Spider was on the gate that was pretty close to those Greater Bee Flies I talked about yesterday. Unfortunately for the spider, those flies don't seem to land very often, and jumping spiders won't typically grab 1 out of the air. (Woe to the Greater Bee Fly that's caught on the ground though.)

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
