Story summary

Researchers found that Iberian harvester ant queens (Messor ibericus) can produce eggs that develop into two species: M. ibericus and M. structor.
This reproductive strategy, called "xenoparity," allows queens to create hybrid workers without mating with M. structor males.
The study analyzed over 120 ant populations in Europe over five years.
M. ibericus queens lost the ability to produce their own workers, relying on M. structor for survival.
This unique phenomenon raises questions about its evolutionary implications and may significantly impact M. ibericus's future.
