Overview

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

Pachygaster leachii faces severe habitat degradation due to intensive agricultural practices and urban development across its European range. The species' dependence on specific microhabitats within wetland margins makes it particularly vulnerable to drainage and water table modifications. Climate change compounds these pressures by altering the moisture regimes essential for its larval development in decaying organic matter.

Threat summary

Habitat

This soldier fly species inhabits wetland margins, marshy areas, and damp grasslands where larvae develop in decomposing organic matter and waterlogged soils. Adults are typically found near shallow water bodies, drainage ditches, and areas with abundant decaying vegetation.
