A new species of tropical ant has been discovered in the vomit of a diablito, or little devil frog, a very orange and poisonous frog that lives in Colombia and Ecuador.
Scientists use wild ant-eating frogs as tiny scouts who are able to search for insects in places people can't go. Then they capture the frogs and carefully make them vomit up the results of their latest explorations. The frogs are released unharmed.
In this case, the frog puke contained a single (and dead) member of the newly identified ant species, Lenomyrmex hoelldobleri. "Sometimes people think that our world is very well explored. Nothing could be farther from the truth," said Christian Rabeling of the University of Rochester, New York, who led a study on the new ant. He added, "The difficulty is finding the ants!"
