Electric Nematodes and Flying Spiders

Electrostatic attraction is not a mating strategy, but as you know, Ze Frank will take any opportunity for a double entendre. This video starts off telling us about nematodes, which are weird enough, but eventually gets to the subject matter: how they harness the tiny electrical charges in the atmosphere for their own ends. For nematodes, it's how parasitic species target flying insects to invade. For bees and other pollinating insects, electric fields offer a strategy for collecting plenty of pollen. That benefits the plants, too. Spiders use electrostatic charges to weaponize their webs into more powerful insect traps. And newly-hatched spiders use the power of electrons to spread their silky parachutes and fly. The concept of parasitic nematodes and flying baby spiders might be icky, so instead think about how these tiny creatures understand the physics of the world around them better than you do.
