Temperature, that is to say, the weather, can affect the determination of sex in insect offspring, says new research out of the University of Montreal in Canada.

According to a study led by Joffrey Moiroux and Jacques Brodeur of the school’s Department of Biological Sciences, and published in the May issue of the journal Animal Behaviour, an insect will either have a male or female offspring depending on how hot or cold the climate happens to be.

“We know that climate affects the reproductive behavior of insects. But we never clearly demonstrated the effects of climate change on sex allocation in parasitoids,” Moiroux said in a news release.
