Platycheirus altomontis

Platycheirus altomontis is a hoverfly (family Syrphidae) belonging to a genus whose members are known for their role as pollinators and, in larval stages, as predators of soft-bodied insects such as aphids. As its name suggests, this species is associated with high-altitude montane environments, where it likely occupies alpine meadows, rocky slopes, or subalpine grasslands offering the flowering plants adult hoverflies depend on for nectar and pollen. Classified as Critically Endangered (CR) by the IUCN, Platycheirus altomontis faces an elevated risk of extinction in the wild, reflecting a combination of restricted range, specialized habitat requirements, and vulnerability to environmental change typical of high-elevation insect species.

Montane and alpine habitats are increasingly affected by warming temperatures, which can shift suitable climatic zones upward until species run out of habitat, as well as by changes in land use and grazing pressure at lower elevational margins. Population trend data for this species remains unknown, underscoring a broader challenge in invertebrate conservation: many narrow-range montane insects are poorly monitored despite facing serious threats. On a more encouraging note, growing interest in alpine biodiversity surveys and pollinator conservation initiatives across mountain regions is beginning to close these knowledge gaps, and increased taxonomic and ecological attention to Platycheirus hoverflies in recent years offers hope that targeted conservation assessments and habitat protections could be developed for this species.

Continued survey work, formal population monitoring, and protection of high-altitude flowering habitats will be essential to securing its future.

This hoverfly species inhabits high-altitude alpine meadows and grasslands, typically found above the treeline in mountainous regions. It requires specific microclimatic conditions with particular flowering plants that provide nectar sources and suitable breeding substrates in these harsh, cold environments.
