Nutritional Symbionts: Why some Insects Don’t Have to Eat Their Vegetables- “While many animals, like humans, consume a varied diet to get these nutritional components, some insects have learned how to cheat the system and can extract nourishment from a nutritionally poor food source through symbioses with bacteria. A symbiosis is a long-term interaction between two different species.” (Laura Kraft, North Carolina University for Entomology Today.) http://bit.ly/2jwr6Ci
