Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Sphaerophoria chongjini faces significant pressure from agricultural intensification and pesticide use across its limited range in East Asia. Urban expansion and industrial development have fragmented its preferred wetland and grassland habitats, while climate change is altering the seasonal flowering patterns of native plants crucial for its survival. The species' specialized feeding requirements make it particularly vulnerable to changes in plant community composition.
