I’ve seen that. When I was younger, we lived in the Appalachian region of the U.S. and every year we’d find a handful of hatchling and juvenile ringneck snakes (Diadophis punctatus) caught in low, ground-touching spider webs. Usually in the walk-in basement, coal room, or up in the storage warehouse - places with concrete floors. I suspect that the tiny snakes couldn’t get enough traction on the smooth floor to pull away from the web after slithering into it.
When found, some were alive and could be freed. Others were already dead or decaying. Sometimes spiders were present in the webs, and a few times appeared to be feeding on the captured snake. Some snakes were still touching the ground when we encountered them, and live ones would attempt to slither but couldn’t make progress. Others had their bodies elevated an inch or two off the ground. I don’t know if the spiders spent time progressively pulling them up with silk lines, or if the thrashing of the snakes ended up tightening silk and lifting them. Either way, interesting stuff.
