All abuzz about sustainability

This female golden digger wasp (Sphex ichneumoneus) is excavating a burrow in front of Building 8. This colorful wasp will only be alive for another month or two, so she needs to quickly prepare a place to lay eggs. Although adult golden digger wasps feed on plant nectar and sap, their young feed on the bodies of other insects. This female will paralyze grasshoppers and crickets with venom from her stinger and drag or carry their bodies into her burrow. Once in the burrow, she will lay an egg on the paralyzed insect’s body and close the burrow entrance. During the next 10 months, the egg will hatch and grow. Next summer, another generation of golden digger wasps will emerge from the ground and repeat the behavior. This wasp species is one of many that have this type of behavior and lifecycle. Other wasp species prey upon cicadas, caterpillars, spiders and even other wasps.
