Larvae of the darkling beetle Tenebrio molitor (shown here) are known as yellow mealworms, and they are widely studied and mass-produced for various animal-feed uses. And, in January 2021, the European Union declared them safe for human consumption. However, a larger relative, Zophobas morio, offers similar potential but has not received the same research and regulatory attention. (Photo by Christos I. Rumbos, Ph.D.)
