Catching food spider style

Navigating a sticky trap
Because a spider has only two body segments, it is technically not an insect. In fact, spiders love to eat insects. To catch food, some spiders use special glands to create silken threads and build a web, a task that’s usually done at night and can be completed in as little as 30 minutes. Some, but not all, of the silky strands are sticky and serve to entangle prey. If you’re wondering why spiders don’t get caught in their own webs, it’s because they tend to remember which strands are which, and just to be safe, they coat their legs with an oily substance that keeps them from sticking.
