This episode explores six stories from the world of arthropods: an alien-looking aquatic insect used to track stream health, Chicago's long-running reputation problem with bed bugs, a spider study on web-building under competition, ancient evidence of silkworm cultivation that predates the Silk Road, a major new tick research initiative,and a community science program tagging living-fossil horseshoe crabs. From the streambed to the beach, host Nathan looks at what these six-legged, and sometimes eight-legged, neighbors can teach us.
