Another one for National Moth Week. The cecropia moth is North America’s largest native moth, and can be found all across the continent. Females have been documented with a wingspan of five to seven inches (125 – 175 mm) or more. Like other members of the giant silk moth family, the cecropia moth lacks functional mouth parts and a digestive system. Due to this, they survive approximately two weeks. So if you get to see one, rejoice!
