The species is known from Florida and surrounding regions of the southeastern United States. Like other members of its genus, it likely exhibits Batesian mimicry of stinging Hymenoptera, though specific biological details remain poorly documented in the available literature.
Polybiomyia bellardii
Red-legged Wasp Fly
A small hoverfly (Syrphidae) known for its striking wasp-mimicking appearance. The species exhibits Batesian mimicry of vespid wasps, with a slender body and contrasting coloration. Adults have been documented across multiple observations, though detailed biological studies remain limited. The common name refers to its distinctive red leg coloration.

Polybiomyia macquarti is a species of hoverfly in the family Syrphidae, first described by Shannon in 1925. It is known by the common name Short-horned Wasp Fly. As a member of the tribe Cerioidini, it belongs to a group of syrphid flies that exhibit wasp mimicry. The species is documented in the Catalogue of Life and GBIF with accepted taxonomic status. Available records from iNaturalist indicate it is rarely observed, with only 12 documented observations.
Polybiomyia townsendi
Yellowshield Wasp Fly
Polybiomyia townsendi is a species of hoverfly in the family Syrphidae, subfamily Eristalinae, tribe Cerioidini. It is commonly known as the Yellowshield Wasp Fly.

The genus belongs to a group of hoverflies that exhibit Batesian mimicry of stinging Hymenoptera.
Sphiximorpha cylindrica
Sphiximorpha cylindrica is a species of hoverfly in the family Syrphidae, described by Curran in 1921. It belongs to the tribe Cerioidini within the subfamily Eristalinae. The genus Sphiximorpha is known for species that exhibit Batesian mimicry, resembling stinging Hymenoptera such as wasps or bees. As with other members of this genus, S. cylindrica likely possesses a cylindrical body form consistent with its specific epithet.
