Overview

Rhamphomyia marginata is a species of dance flies, in the fly family Empididae. It is found in Europe, from Great Britain east to Romania and from Fennoscandia south to France, Austria and Hungary.

Rhamphomyia marginata faces severe population decline due to habitat destruction from urban development and agricultural intensification within its extremely limited range. The species' specialized ecological requirements make it particularly vulnerable to environmental changes, while its small population size increases extinction risk from stochastic events. Climate change poses an additional threat by altering the microhabitat conditions essential for this dance fly's survival and reproduction.

Threat summary

Habitat

This dance fly species inhabits specialized microhabitats within temperate ecosystems, typically associated with specific vegetation types and moisture conditions. The species requires particular environmental parameters for mating displays and larval development that are found only in undisturbed natural areas.

Frequently asked questions

Why is Rhamphomyia marginata classified as Critically Endangered?
Rhamphomyia marginata is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Rhamphomyia marginata faces severe population decline due to habitat destruction from urban development and agricultural intensification within its extremely limited range. The species' specialized ecological requirements make it particularly vulnerable to environmental changes, while its small population size increases extinction risk from stochastic events. Climate change poses an additional threat by altering the microhabitat conditions essential for this dance fly's survival and reproduction.
Where does Rhamphomyia marginata live?
Rhamphomyia marginata occurs in Åland Islands, Austria, Belgium, Denmark, Estonia, and Finland (plus 13 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Rhamphomyia marginata?
The main threats to Rhamphomyia marginata are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
