Alphitobius laevigatus, the black fungus beetle, is a species of darkling beetle in the family Tenebrionidae.

[1][2][3][4] A. laevigatus is bred in large quantities for the use as feed for captive birds, reptiles, or amphibians.

The larvae reach a length of up to 15 millimeters.

The larvae are often marketed under the trade name buffalo worms, a name that is also used for the larvae of Alphitobius diaperinus which can lead to confusion.

[5] In difference to A. diaperinus, A. laevigatus is not used or discussed as food for human consumption.
