| 1323029 | fire ant decapitating flies | Pseudacteon spp. | This Brazilian fly makes fire ants literally lose their heads. The South American phorid fly, Pseudacteon , is a highly specific, natural enemy of fire ants. ARS scientists hope to import it for tests in the United States, where fire ants lack natural enemies. They feed on crops and sting people and animals in 11 states. Beheading a live host-a rarity among parasitic flies-is standard procedure for Pseudacteon flies. And they attack only fire ants. The female deposits an egg on or in a fire ant's body. Weeks later, a maggot has moved through the unlucky ant's neck into its head-and eaten the contents. The head falls off after an enzyme-made by ant or maggot (scientists don't know which)-dissolves its connecting tissue. |
| 1319015 | fire ant decapitating flies | Pseudacteon spp. | Fire ants will try hard to avoid the sting of a phorid fly (top, center). Once deposited, an egg quickly hatches into a larva that eventually kills the host by decapitation. Shown about nine times actual size. |
