The first photo is of a cousin to the wooly bear caterpillar, the spotted tussock moth caterpillar (Lophocampa maculata). The white hairs sticking out of this caterpillar have stinging barbs, so watch out. They feed on deciduous trees. This one was traveling across the forest floor.
The second photo is what looks like the fall webworm (Hyphantria cunea). This caterpillar has a huge variation in its appearance, so i'm not 100% sure of the ID. I saw this caterpillar crawling across a thimble berry leaf. I didn't think to look in the trees overhead to see if the rest of its webmates were nearby, but they aren't usually found alone.
The last photo is the common thread-waisted wasp (Ammophila procera) on some late blooming goldenrod i found on my plot. These are great beneficial wasps, often seen carrying caterpillars back to an underground lair for their young. The adults feed mostly on nectar and are quite effective pollinators. If you zoom in, you can see that the face, body, and legs of this wasp are covered in pollen. As a bonus, there is a crab spider hiding in the goldenrod blooms. He was so well camouflaged, i didn't even notice him when i took the photos.
