Feasting On Flies

posted on November 17, 2000

Fire ants … a feast for flies.

The USDA will release hundreds of thousands of tiny Brazilian flies to destroy fire ants that are wreaking havoc for farmers, homeowners and wildlife.

The gnat-like flies like to hover over ant mounds before darting down and injecting a torpedo-like egg into the ants. After the eggs hatch, the maggot decapitates the ant by eating the brain and other contents of the head.

The Ag Department says, while the flies don't kill enough of the fire ants to destroy colonies, they do cause enough panic to keep the ants in check.
