Well, this kind of scrambles the definition of a 'species'.

These Ant Queens Seem to Defy Biology: They Lay Eggs That...

Iberian harvester ant queens produce offspring of their own species and of the builder harvester ant, seemingly by cloning males

Coming from microbiology, the concept of species was pretty scrambled to begin with. I have made peace with that by realizing that categories are essentially post-hoc models and they may or may not conform to nature. More important is whether they are useful and to realize when their usefulness ends. Basically the whole the map is not the territory issue.

Maybe I should add this to the 'Today I Learned' thread ...

How interesting. It’s akin to the ants farming another useful species, something that ants are known to do, but here the ants are doing so by reproductive means. It’s an example of natural genetic engineering.
