Please naming this bug eggs? nest? Or what?

What is this? Thanks ahead

To my noob eyes, it looks like a spider's egg sac.

I mean, this plant is an outdoor plant, so I would guess that bugs are a fairly frequent hitchhiker. Predators are probably welcome, mostly at least.

Looks very much like a caterpillar nest to me. Lots of eggs in there.

Cut the leaf off, take it to a well lit, safe, and clean place, then cut it open to inspect it... with a loupe or other magnifying glass to inspect closer?

Thanks guys I have it in a sealed mason jar waiting for them to hatch now

i can’t tell if there are lots of eggs in there or not as it’s not clear enough but I’ve seen mealy bugs lay similar looking sacks.

Spread it on toast
