gulhuvad skaftstekelfluga
ENPhysocephala vittata
Physocephala vittata, a thick-headed fly species, faces severe population declines primarily due to habitat loss from agricultural intensification and urbanization of its specialized grassland and meadow habitats. The species' parasitic lifestyle, which depends on specific host bee and wasp species, makes it particularly vulnerable to disruptions in pollinator communities caused by pesticide use and habitat fragmentation.

Gull-billed Tern
CRGelochelidon nilotica
