Striped Horsefly

Hybomitra expollicata

Unknown

Overview

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

The Striped Horsefly faces significant population declines primarily due to wetland habitat destruction and degradation across its European range. Agricultural intensification and urban development have eliminated many of the marshy areas and wet meadows essential for its larval development. Climate change is altering precipitation patterns and temperature regimes in its breeding habitats, while pollution from agricultural runoff degrades water quality in remaining wetland sites.

Threat summary

Habitat

The Striped Horsefly inhabits wetland environments including marshes, wet meadows, and boggy areas across northern and central Europe. Adults require proximity to water bodies for reproduction, while larvae develop in saturated soils and shallow water margins of these wetland systems.
