From it’s motion I imagine a spider on the upper end of the thread, trying it’s darndest to try to haul that flower up, or perhaps flying it purposefully, like a kite, or fishing for humans 🙂 – for whatever reason a spider or caterpillar would think it’s a great idea to do that. I wonder if all species have the odd ducks who do different things that make no sense to the rest of their kind.
