Are these what I think they are?

[JeffInCanada]

I'm with SoOrbudgal and JohnEmad if they are not going to cause you any trouble, let them be...they are almost at their flowering stage At the same time, if you are worried about them causing you issues with outdoor grows I'd understand spraying them.

[JohnEmad]

Why spray them? Are they a big threat to...? I would be happy to see them up close when they are fully formed in all their splendour.

[Bowhunterwoody]

Yep. They are pretty big too. Found a dead one at the cabin that was over 6" across. Beautiful too.

[SoOrbudgal]

Well i think they are special

JeffInCanada Thanx, I'll mix the spray as these are not near a garden! I need to spray for tent caterpillars anyway.

BT?....whodat?

[JeffInCanada]

They are used covid masks caught in the tree. From over the winter......just kidding. I think CaptainWiese91 was correct. Best I can find is a big ass moth. The Promethea Moth. My guess is this or something similar to this.

BT you're fine.

Where the hell is Admiral Kirk when you need him!?

Don't touch them, they could be alien body snatchers! (sorry, just saw that rerun on tv) You could try to smoke one...they look nicely rolled. I think some kind of moth cocoon which reminded me that the last 2 nights at lights on I inspected my ladies just at lights on at 9pm. Both times as I started to close up I saw a tiny white moth flitting around in my cabinet. I tried to swat it but it has so far eluded me. My great fear is getting a caterpillar infestation at 7 weeks in. Tonight I will tear the cab apart to find it. If it has already laid eggs I'm screwed.

Some things in nature just look "leave me alone".

How interesting if you decide to remove it please take photo of it closer and Thank You for posting this

[Tumbleweed]

Definitely Ceti Eels. I'd wear ear protection and maybe a nose clip when removing them.

[Floopydoop]

If I were you I'd start running now.
