Tufted Globetail

Here's a Tufted Globetail from last spring. They are hoverflies in the globetail genus, which gets its name because the males have tails (actually abdomens) that end in little globes. (In this species the tail is more "thick and rounded" rather than a globe.) If this individual was a female, the abdomen would have ended in more of a point. I generally expect these flies to have more prominent black stripes on the abdomen, though I'm not sure how much variation they can have.

If you were thinking this was a wasp, the hoverfly is doing its job; most hoverflies are wasp/bee mimics who "impersonate" stinging insects to get some of the protection their stinging look-alikes command. Although they can be found throughout most of North America, they're especially prevalent in Canada and the northern US.

Hoverflies are also called "flower flies" (also syrphids) because as adults they're basically pollinating insects who hang around flowering plants, in this case a Common Yarrow. Some other syrphids I've shown are the Margined Calligrapher Fly, Common Drone Fly, European Drone Fly, Transverse-banded Flower Fly, and Eastern Calligrapher.

Although they're vegetarians as adults, as larva they need their protein and eat small arthropods. Aphids are at the top of the menu but mites, thrips, and lepidopterans will do in a pinch.

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
