Platycheirus transfugus

UnknownLCEULCEU

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Platycheirus transfugus faces significant pressure from habitat degradation in its specialized wetland environments. Agricultural intensification and drainage of bog and fen systems have reduced the availability of suitable breeding sites. Climate change poses additional risks through altered precipitation patterns that affect the moisture levels critical for this species' larval development in semi-aquatic habitats.

Threat summary

Habitat

This hoverfly species inhabits specialized wetland environments including bogs, fens, and marshy areas with abundant moisture. The larvae develop in semi-aquatic conditions among decaying organic matter, while adults are typically found on flowers in adjacent meadows and bog margins.
