Inside-Out Killer

For more than a decade scientists at the USDA's Agricultural Research Service have sought an environmentally friendly method of controlling the sharpshooter, and a South American wasp may fit the order.

Gonatocerus tuberculifemur wasps are 15 to 20 times smaller than sharpshooters, but it's their even smaller offspring that kill off the sharpshooters. They lay eggs inside the sharpshooter's eggs, and when the young wasps emerge from their eggs, they eat the sharpshooters' eggs from the inside out.
