Overview
The Big-spotted Cleg (Haematopota bigoti) is a large horse fly species distinguished by its prominent dark spots across pale wings and robust build. As a blood-feeding insect, females play important ecological roles as both disease vectors and prey for various bird and spider species, while also serving as pollinators when feeding on nectar.
The Big-spotted Cleg (Haematopota bigoti) faces significant population declines primarily due to habitat loss and degradation of its specialized wetland environments. Agricultural intensification, urban development, and climate-induced changes to water regimes have severely reduced the availability of suitable breeding and feeding habitats for this blood-feeding fly species.
Habitat
Big-spotted Clegs inhabit marshy areas, wet meadows, and the edges of slow-moving streams where females lay eggs in moist soil. Adults are commonly found near grazing areas and woodland clearings where they seek blood meals from livestock and wild mammals.
