Sex ant

The sex life of fire ants has shed light on how new species may arise, according to a report in the 17 October issue of Nature. If populations are isolated geographically from one another, they can eventually evolve into several new species. Biologists have speculated that restrictive mating practices can also isolate populations and trigger speciation. Now a team led by Kenneth G. Ross, an entomologist at the University of Georgia, Athens, offers evidence for the process in fire ants. Analyzing DNA from different colonies, Ross's team found an unusual pattern of gene flow from one generation to the next.

Sex wars: Ant queens take sperm from males of other species

Scientists studying the habits of two related species of harvester ants have discovered that during sex, the queens will essentially steal sperm from unwitting male ants of the other species. The findings, published in the Proceedings of the Royal Society B, shed light on the evolutionary arms race between two species that can play out in a battle of the sexes. Researchers from the University of Vermont studied two species of Pogonomyrmex harvester ants that live in the desert around the border between Arizona and New Mexico. These two ant species can mate with each other, but these liasons only produce sterile hybrid ants. If he wants grandkids, a male has to avoid those inter-species hook-ups and find a queen of his own species to mate with.

Even ants can't completely swear off sex. A new survey of a Latin American species famed for being one of the world's few asexual ants has uncovered a surprising find: secret nooky. And that could explain why the insect has managed to survive for so long.
