Mermithergate

A mermithergate is an ant worker that has a changed appearance as a result of a Enoplia nematode infection. The word was coined by William M. Wheeler in 1910.〔Wheeler 1910〕 It is a combination of the nematode genus ''Mermis'', for which Wheeler first described the phenomenon, and ergate, which means ant worker. Infected females (queens) are called mermithogynes.
Up to five percent of some populations of ''Cephalotes atratus'' suffer from an infection by the tetradonematid nematode ''Myrmeconema neotropicum''. It causes the ant's abdomen to turn from black to bright red, strikingly resembling a red berry. In addition, the ant now holds it up most of the time, and it is easily ripped off. Birds easily mistake these for real fruit and pick them, while they avoid eating normal ants. The nematodes pass through the bird's digestive system as eggs without harming it. The circle closes when ''C. atratus'' workers feed on the bird droppings, thus getting infected.〔University of California: ( Ant parasite turns host into ripe red berry, biologists discover ) — Retrieved on 2008-01-20.〕
