Cerambycidae (insecta: Coleoptera) preyed by Speotyto cunicularia (aves: Strigiformes), with a revision of bibliographical references for the western hemisphere

A review on the Cerambycidae (Insecta Coleoptera) preyed by the burrowing owl, Speotyto cunicularia (Aves Strigiformes) in America is presented, together with new records from Argentina. At least 28 specimens of Cerambycidae were found among other prey for all American subspecies of S. cunicularia, from which 8 specimens were identified only to family level, and 20 to specific level (18 specimens belong to a single species). For the whole Argentina, 14 specimens of Cerambycidae were found in the diet of S. c. partridgei, representing 0.24% of total prey recorded (Ramírez Llorens, 2003). Intensive samplings were made in La Pampa and Buenos Aires provinces, while collectings from other localities were occasional. A total of 420 specimens belonging to 18 species of Cerambycidae were individualized from regurgitated pellets. A ranking of the preyed species is presented and discussed in light of the known biology of the Cerambycidae from the country. The most preyed species is Phoracantha recurva Newman, 1840, an exotic Cerambycidae naturalized in Argentina.
