Irish Major

Oxycera fallenii

Unknown

Overview

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

The Irish Major faces severe habitat degradation due to agricultural intensification and drainage of wetland areas across its limited range. Urban development and infrastructure projects have fragmented remaining suitable habitats, while pollution from agricultural runoff degrades water quality in the marshy environments this species requires. Climate change poses additional pressure through altered precipitation patterns affecting the moisture levels critical for its larval development.

Threat summary

Habitat

The Irish Major inhabits marshy areas, wet meadows, and the margins of slow-flowing streams and ditches, particularly in lowland regions. This soldier fly species requires consistently moist environments with organic-rich substrates where its larvae can develop in decomposing vegetation and muddy sediments.
