Adam Ruins Everything 3x10

Adam reveals to a woman getting ready for a party how spiders actually benefit humanity, how bug parts are hidden inside everyday foods and a whole insect can be more nutritious than part of conventional livestock, and some bugs actually help the human body function properly. Between the segments about food and the human body, Emily discusses what actually happens when a caterpillar becomes a butterfly; and, at the end of the episode, she discusses the eradication of mosquitoes.
