Spined oak borer, Elaphidion mucronatum (Say 1823) and Pteromalid parasitoid.

The spined oak borer is a longhorned beetle native to the eastern parts of the United States, including Minnesota, Nebraska, Kansas, Oklahoma, and Texas. Horismenus is an Eulophid parasitoid wasp found along with spined oak borer. The relationship between the spined oak borer and Horismenus, represents a classic example of biological control in nature, where one species helps regulate the population of another.
