New records of the exotic Band-eyed Drone Fly, Eristalinus taeniops (Wiedemann, 1818) (Diptera, Syrphidae), in Argentina

Abstract

Eristalinus (Eristalodes) taeniops (Wiedemann, 1818) is a pollinator hoverfly native to the Old World that has spread through several countries in America. We determine the current distribution of this species in Argentina by using records from scientific literature and citizen science websites. In addition, we report the first three specimens collected in Córdoba province. Eristalinus taeniops is present in 10 provinces in Argentina and seems to be more frequent in anthropized habitats. Likewise, the specimens we collected were exclusively captured within the city of Córdoba. Our results confirm the occurrence of E. taeniops in central Argentina and contribute to determining the actual geographic distribution of this species in the country. Our new data could help to evaluate the potential invasiveness of E. taeniops in ecosystems.
