Spilomyia texana
Texas Hornet Fly
Spilomyia texana is a hover fly (family Syrphidae) first described from Texas in 1921 by Johnson. The species is currently treated as a synonym of Spilomyia alcimus (Walker, 1849), the Broad-banded Hornet Fly, by major taxonomic databases including GBIF and Catalogue of Life. Like other members of the genus Spilomyia, it is a wasp mimic with yellow and black coloration. The genus contains approximately 13 species in North America, all known for their convincing mimicry of yellowjackets in both appearance and behavior.
