Mirror image pheromones help beetles 'swipe right' to find mates

There are many ways to communicate with prospective romantic partners. If you are a Japanese scarab beetle, it's a matter of distinguishing left from right. New work from U.S. and Chinese scientists, published this week in Proceedings of the National Academy of Sciences, shows how these beetles use mirror-image pheromones to find a mate. The work could lead to better monitoring and control of significant agricultural pests.
