Mastogenius crenulatus
Mastogenius crenulatus is a species of metallic wood-boring beetle in the family Buprestidae, first described by Knull in 1934. It is one of the smallest buprestids in North America, measuring approximately 2 mm in length. The genus Mastogenius is characterized by its diminutive size and cryptic dark coloration, making adults appear as tiny black dots on vegetation.
