Identification
are small, slender flies with reduced wing venation compared to other Empidoidea. Larvae are elongated, cylindrical, and adapted for life in fast-flowing water, with suckers for attachment to submerged substrates.
Habitat
Associated with lotic (flowing water) including streams and rivers; larvae are aquatic and attach to rocks and other submerged substrates in fast currents.
Distribution
Documented from the Palearctic and Nearctic regions; specific distributions vary but the has been recorded across northern and central Europe, Asia, and North America.
Life Cycle
Larvae are aquatic and undergo development in fast-flowing freshwater; occurs in or near the water. are short-lived and primarily reproductive.
Behavior
Larvae use suckers to maintain position in fast currents, a specialized for rheophilic (current-loving) life. are weak fliers and remain near larval .
Ecological Role
Larvae contribute to benthic macroinvertebrate in streams; their presence indicates well-oxygenated, fast-flowing water conditions. They may serve as prey for aquatic including fish and other .
