Researchers discovered that males of the yellow crazy ant have maternal and paternal genomes in different cells of their body and are thus chimeras. The yellow crazy ant, or Anoplolepis gracilipes, ...

Yellow crazy ants (Anoplolepis gracilipes) are, to put it simply, one of the more well known aggressive 'jerks' of the ant world. And that's saying a lot for any of the countless number of invasive ...

Intense male-male competition continues even after mating has taken place in Atta ants. This study showed that in both ant and bee species in which queens have multiple mates, a male’s seminal fluid ...

Researchers have discovered the genetic basis for a quirk of the animal kingdom -- how ant queens produce broods that are entirely male or female. Researchers have discovered the genetic basis for a ...
