ELI5: How do some spiders manage to get stuck in the webs of other spiders despite being able to (seemingly) flawlessly move through their own webs?
gpt
Not all strands in a spider web are sticky, and a spider moves on his own web by walking on the non-sticky strands. If the spider stepped incorrectly, they'd get stuck in their own web.

If that same spider tried to walk on a different web, they'd probably step on the wrong strand and get stuck.
