baltisk sandstilettfluga
Acrosathe baltica
Overview
The Baltic sand stiletto fly (Acrosathe baltica) is a specialized predatory dipteran with a distinctive elongated proboscis and slender build, measuring 8-12mm in length with characteristic amber-tinted wings. This species plays a crucial ecological role as both predator and prey, feeding on smaller arthropods in sandy coastal environments while serving as an important food source for coastal birds and spiders.
Acrosathe baltica faces severe population declines primarily due to habitat loss from coastal development and agricultural intensification in its limited Baltic coastal range. Climate change and sea level rise pose additional threats to its specialized sandy coastal habitats, while the species' restricted distribution makes it particularly vulnerable to local extinctions.
Habitat
Acrosathe baltica inhabits loose, well-drained sandy soils within 200 meters of the Baltic Sea coastline, particularly favoring areas with sparse vegetation and organic debris deposits. The species requires specific microhabitats where sand temperature and moisture levels remain stable, typically found in the transition zones between active dunes and established coastal vegetation.
