Alphitobius laevigatus
Black Fungus Beetle
Alphitobius laevigatus, commonly known as the black fungus beetle, is a darkling beetle in the family Tenebrionidae. The species is native to Europe and has been introduced to North America and other regions including the Galápagos Islands. It is commercially bred in large quantities as animal feed, with larvae marketed under the trade name "buffalo worms"—though this name is also used for the related Alphitobius diaperinus, causing potential confusion. Unlike A. diaperinus, A. laevigatus has not been used or discussed for human consumption.
