This is a regularly tapering tube made out of sand grains and hardened mucus, created by a polychaete in the family Pectinariidae.

The one is a little bit broken -- not really intact otherwise it would be longer and a bit more curved.

It accidentally fell into the dish of pond water.

We found two of these.

We were examining pond water, but perhaps one larva dropped from the tree above us, or maybe they both just crawled up the side of the dish.

??

To me it seemed unlikely that this was either of the two more common species, as the leaves on this one are really huge, like 4 inches long.

But I really don't know how to ID the Hornbeam Copperleaf , especially considering this plant is not in flower or fruit.

So I could be completely wrong.

Could this just be a giant example of Common Copperleaf?

This louse was sitting on a leaf of a small plant growing out of the shady wall in Carl Schurz Park. I let it crawl onto my glove, photographed it and then made sure to put it back on the plant again.

It was a decent size, maybe about 3.5 mm, or possibly 4 mm?

I wonder what species of mammal or bird it had been living on?

A human???

A dog?

A pigeon?

I have no idea.

The trunk of this pin oak street tree has thousands of these tiny white things on it.

The tree also has masses and masses of galls of the Horned Oak Gall.

Quite a lot of the smaller branches are dead.

These are on the trunk of a Pin Oak street tree, which is also shown in the observation before this one.

These do not move at all. They are very tiny (2 mm or 2.5 mm) and they are a whitish cream in color. A vast number of them are attached to the tree trunk. Some of them have a hole in their surface.

Hard to see any detail at all. When I went back with a good hand lens I could see they were fibrous on the inside.

These are self-seeded seedlings of Japanese Aucuba, and therefore these seedlings are wild by iNat standards.

However, I am not clear if that makes the Badnavirus in them "wild" or not.

I would think probably not?

@jameskdouch -- what do you think?

On a small leaf of a sucker of Callery Pear street tree.

I am assuming it is very recently emerged, and that it left the final nymph exoskeleton beside it.

Good close shots of the nymph exoskeleton are here:
