Japanese Honeysuckle

Here's another invasive plant species, the Japanese Honeysuckle. And it's engaged in invasive-on-invasive violence, beginning its classic climb-and-strangle strategy on yesterday's invasive plant, the Japanese Angelica Tree. My impression is that all those prickles on the Japanese Angelica Tree won't save it; the Japanese Honeysuckle will presumably maneuver between them as it climbs.

I'm not sure what happens to mature trees when Japanese Honeysuckle moves in. I'm sure they'll climb the trees and that it's foliage will compete with the tree's foliage for sunlight. I know that Japanese Honeysuckle will kill young trees as they wind themselves tightly around the trunk, so I suspect it'll also damage newer tree branches even if thick bark protects the main trunk from the Japanese Honeysuckle.

If there's nothing to climb, Japanese Honeysuckle will form thick clusters that catch almost all the sunlight, making it very difficult for any other plants to even successfully germinate.

Unlike some invasive plants, it sounds like the foliage can be eaten by at least some of our herbivores, though given how much of it I see by the end of winter I suspect it's not the favorite meal for our deer population.

If the plant isn't too mature, you're probably better off pulling it out by the roots, though it sounds like if any rhizome remains the Japanese Honeysuckle may be able to resurrect itself.

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
