dennendidea
Didea intermedia
Didea intermedia is a medium-sized dipteran fly characterized by its distinctive metallic green thorax and amber-tinted wings with dark banding patterns. This specialized pollinator plays a crucial role in montane ecosystems, serving as a primary pollinator for several endemic alpine flowering plants while also functioning as a key prey species for insectivorous birds during summer months.

Species Profile
Didea intermedia is a medium-sized dipteran fly characterized by its distinctive metallic green thorax and amber-tinted wings with dark banding patterns. This specialized pollinator plays a crucial role in montane ecosystems, serving as a primary pollinator for several endemic alpine flowering plants while also functioning as a key prey species for insectivorous birds during summer months.
Didea intermedia faces significant pressure from habitat loss due to deforestation and agricultural expansion across its range. Climate change is altering precipitation patterns and temperature regimes in its forest habitats, while fragmentation isolates populations and reduces genetic diversity.
