Wasp Wood-soldierfly

Xylomya maculata

Unknown

Overview

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

The Wasp Wood-soldierfly faces severe population decline primarily due to the loss of ancient woodland habitats containing the dead wood microhabitats essential for its larval development. Intensive forestry practices that remove fallen logs and standing dead trees have eliminated critical breeding sites across much of its historical range. Climate change compounds these pressures by altering the moisture and temperature conditions within decaying wood that larvae require for successful development.

Threat summary

Habitat

This species inhabits ancient deciduous and mixed woodlands, particularly those with abundant dead wood in various stages of decay. The larvae develop within rotting logs and fallen timber, requiring specific moisture and temperature conditions found in undisturbed forest floor environments.

Frequently asked questions

Why is Wasp Wood-soldierfly classified as Endangered?
Wasp Wood-soldierfly is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. The Wasp Wood-soldierfly faces severe population decline primarily due to the loss of ancient woodland habitats containing the dead wood microhabitats essential for its larval development. Intensive forestry practices that remove fallen logs and standing dead trees have eliminated critical breeding sites across much of its historical range. Climate change compounds these pressures by altering the moisture and temperature conditions within decaying wood that larvae require for successful development.
