Butterflies are light and delicate and catch our eyes with an amazing variety of vivid colors as they flutter about. This is all due to some insanely complex and intricate systems that they’ve evolved. The way they fly through the air involves astonishing physics tricks. Their colors have different purposes, and come about through different schemes. Add those tricks to the weird way they transform from a caterpillar to something completely different, and you have to wonder why they didn’t just take over the world while they’re at it. The physiology of a butterfly is mind-blowing, but for some reason, we don’t have as much respect for moths. Maybe that’s because butterflies won’t eat our winter coats. Moths are a lot like butterflies, but they fly at night, so we don’t pay as much attention because we just don’t see them as much. Anyway, you’ll learn a lot from the latest episode of Ze Frank’s True Facts series. There’s a one-minute skippable ad at 7:14.
