Mallota mississipensis
Eastern Mimic Fly
Mallota mississipensis is a of hover fly ( Syrphidae) in the Eristalinae. It is one of approximately 13 species in the Mallota found in North America. The species is a mimic, exhibiting the black and yellow coloration typical of this defensive mimicry strategy. Like other members of its genus, the larvae develop in aquatic or semi-aquatic environments, specifically in water that collects in tree holes. The species is known from eastern North America, with observations documented in the iNaturalist database.

Identification
Mallota mississipensis can be distinguished from the more common Mallota posticata by subtle differences in yellow markings and body proportions. Identification to level typically requires examination of microscopic characters. The Mallota is characterized by larvae that develop in tree holes, and that often perch on leaves to groom and feed on pollen.
Habitat
are found in woodland , often near flowering plants. Larvae develop in water that collects in tree holes, a specialized aquatic microhabitat.
Distribution
Eastern North America. Documented observations include records from the eastern United States.
Diet
feed on pollen. Larvae filter bacteria and other microbes from organic matter in aquatic environments.
Life Cycle
are laid in water-filled tree holes. Larvae are aquatic, possessing a breathing siphon to access air at the water surface. They filter-feed on organic detritus and microorganisms. Mature larvae seek dry ground to pupate in a hardened capsule. emerge and are active during warmer months.
Behavior
frequently use leaves as platforms for , often adopting contorted postures to clean their bodies. They are , visiting flowers to feed on pollen.
Ecological Role
serve as . Larvae contribute to nutrient cycling in aquatic microhabitats, processing organic matter in tree hole .
Human Relevance
Contributes to pollination services. The specialized larval (tree holes) makes it dependent on mature forests with standing water in cavities.
