Black flies drink blood and spread disease such as river blindness—creating misery with their presence. A University of Georgia study, however, proves that the pesky insects can be useful.

Two years ago, the kudzu bug arrived in Georgia and has been aggravating homeowners and feeding on kudzu and soybeans ever since. Now, some of Georgia’s Latin American trading partners are worried that the legume-eating pest may be headed south.

Nature is a system of checks and balances, as is the case between aphids and wasps. Aphids feed on plants; wasps lay eggs inside aphids, killing them and increasing plant production. Some aphids harbor bacterial symbionts, or smaller organisms that live in close association with a host, that provide protection by killing the internally developing wasps. Wasps are able to decipher which aphids are infected and use superparasitism to override the poison.
