Sphegina lobulifera is a rare syrphid fly known from eastern North America. Adults are flower-visiting insects that obtain nectar and pollen from floral resources. The species belongs to the pufftail group, characterized by distinctive abdominal morphology. Larvae develop in decaying sap accumulations under bark in moist woodland habitats.
Sphegina rufiventris
Black-horned Pufftail
Sphegina rufiventris is a common syrphid fly species found in the northeastern United States. Adults are commonly observed on flowers, where they feed on nectar and pollen. The species is notable for its ability to hover nearly motionless in flight, a trait shared with other hoverflies. Larvae develop in specialized microhabitats, specifically accumulations of decaying sap under bark in moist environments.
