blekbent vedstilettfluga
Cliorismia ardea
The blekbent vedstilettfluga (Cliorismia ardea) is a distinctive stiletto fly characterized by its pale, bent proboscis and slender metallic body with subtle gray-green coloration. This predatory dipteran plays a crucial role in forest ecosystems as both a predator of smaller insects and as prey for insectivorous birds and spiders.

Species Profile
The blekbent vedstilettfluga (Cliorismia ardea) is a distinctive stiletto fly characterized by its pale, bent proboscis and slender metallic body with subtle gray-green coloration. This predatory dipteran plays a crucial role in forest ecosystems as both a predator of smaller insects and as prey for insectivorous birds and spiders.
The blekbent vedstilettfluga faces significant threats from habitat degradation and fragmentation of its specialized wetland environments. Climate change is altering precipitation patterns and water levels in its breeding areas, while agricultural expansion and urban development continue to reduce available habitat.
Key Facts
Habitat & Distribution
This species inhabits marshy areas, wet meadows, and the vegetated margins of slow-moving streams and ponds in temperate regions. It requires areas with dense emergent vegetation and stable water levels for successful breeding and larval development.
Threats
