If we could eliminate insects from the world without messing up the food chain, I'd be all for it. But it appears that the Endangered Species Act doesn't just protect charismatic mammals like elephants and bears and lions, but also picture-wing flies:
Picture-wing flies are about two to three times the size of common house flies and are considered harmless to humans. Other species of picture-wing flies are found outside Hawaii.
The flies are named for the intricate markings on their clear wings and are known for their elaborate performances when protecting their territory or courting a mate.
Two to three times the size of common house flies?!? Yuck!
