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.

Pressure mitigation

Once sites are identified, management and protection of dune areas from human disturbance (trampling) and encroachment of developments i.e golf courses is required

Pressure mitigation

Once sites are identified, management and protection of dune areas from human disturbance (trampling) and encroachment of developments i.e golf courses is required

Targeted monitoring

Targeted surveying by experienced dipterists to ascertain a more accurate assessment of distribution and populations. Possible use of Recording Schemes to promote surveying on a more general basis in suitable areas.

Untargeted habitat management

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