Identification
Belytini can be distinguished from other tribes by the structure of the , which bears a distinct or flange. The typically have 12–14 with a reduced or absent . The usually lacks a and has simplified , with the or absent. These features separate Belytini from the related tribe Pantoclisini.
Habitat
Found in moist, decaying substrates including leaf litter, compost, rotting wood, and fungal fruiting bodies. These support the dipteran that Belytini parasitize.
Distribution
distribution with records from North America, Europe, Asia, Australia, and various island systems. Diversity appears highest in temperate and subtropical regions.
Seasonality
activity generally peaks in spring and summer, though some extend into autumn in temperate regions. Activity patterns correlate with availability and moisture conditions in substrate .
Host Associations

Behavior
Females search for in decaying substrates using olfactory cues. Males are often collected at light or in intercept traps, suggesting . Both sexes are weak fliers with a characteristic hovering flight pattern near substrate surfaces.
Ecological Role
Act as agents of and other dipteran in . Contribute to regulation by limiting populations.
