Spider silk - webs

We just learned about Spider's Silk Balooning When spiders make webs, they use different types of silk.

Some parts of the web like the spoke lines going straight out are not sticky. Those are called ampullate or dragline silk.

Other parts that are sticky and bugs can get caught on are called flagelliform, or capture lines.
