Something is taking just the leaves off my pothos

Hi all. This has me stumped. I went to check on my plants today only to notice that my pothos has all the leaves on the bottom vines just. Gone. I checked everywhere for caterpillars, or anything that could be eating it but see nothing. It’s inside a sunroom. There’s some stringy stretchy stuff at the end of each… nub (pic 3). No pets. I have a weird roommate but I don’t want to accuse her of cutting them or anything until I can fully rule out pests. Has anyone ever seen this? It’s pretty much only on these long vines, and the leaves definitely aren’t anywhere in here. Plant is in leca and is watered normally. It’s inside a sunroom and gets indirect light most of the day.
