This chart should not be relied upon for an indication of species status as variations in recording effort can heavily affect the count of occurrences and occupied 1km squares.

Threatened species recovery actions

Actions from Threatened Species Recovery Actions 2025 Baseline published by Natural England.

Education/awareness raising

Produce a status review of England's dung and carrion invertebrate assemblage including the results of research into the impact of veterinarian livestock inputs on this fauna. This would benefit both this and many other TSRA species.

Habitat management

Implement year round low intensity cattle grazing at sites across the key landscapes. Do not use endectocides. In winter cattle should not be fed in silage, maize or soya since this affects the quality of the dung and its nutritional value to coprophagous invertebrate larvae.

Targeted monitoring

Targeted non-lethal monitoring to assess population trends

Untargeted habitat management

This species would benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages
