Copestylum fraudulentum is a species of hoverfly in the family Syrphidae. It belongs to a genus of bromeliad-associated flies primarily found in the Americas. The species was described by Samuel Wendell Williston in 1891. Like other members of Copestylum, adults are likely associated with flowers and may exhibit mimicry of bees or wasps, a common trait in the Syrphidae family. The larvae of related species are known to develop in bromeliad phytotelmata, though specific larval biology for C. fraudulentum has not been documented.
