Agrilus osburni
Agrilus osburni is a species of metallic wood-boring beetle in the family Buprestidae, described by Josef N. Knull in 1936. It belongs to the extraordinarily diverse genus Agrilus, which contains nearly 4,000 described species and may represent the largest genus in the animal kingdom. The species is known from North America, with records from Canada (Ontario and Québec) and the United States. Like other members of the genus, it is presumed to develop as a larva in woody plant tissue, though specific details of its biology and host associations remain poorly documented.
Sternidius imitans
Sternidius imitans is a species of longhorned beetle in the family Cerambycidae, subfamily Lamiinae. Described by Knull in 1936, this species belongs to a genus that has undergone taxonomic revision, with some species previously synonymized under S. alpha later revalidated. The genus Sternidius comprises small longhorned beetles that are frequently encountered by collectors beating vegetation.
