Food
The caterpillars have been gathered and eaten by Native Americans. After collection, they would be skewered and roasted for a feast, and any leftovers were stored whole or ground up after being dried. The nutritional value of the larvae has been analyzed, and found to be significant; they contain almost as much fat as hamburger meat, but have almost one-third less saturated fat, and more energy, protein, carbohydrate, riboflavin, and niacin than hamburger meat.References:
