I made some spiders for my mod. I found sometimes I'd start in an area and there would be webs around, but my spiders wouldn't make more. They do however, make plenty of webs when they are fighting. My spiders are trainable (war, hunting spiders), so assigning them to a hunter seems to supply me with more webs.
I've been debating if I should add thickweb to them so their webs are useful in combat, but I'm thinking that it might end up deadly to my dwarves if they accidentally get stuck in them.
