Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | The sparse distribution of records for this species may reflect under-recording of stream margins in hill country and evidence of recent decline is weak. Few entomologists record Scirtid larvae to species, which might be an easier way of detecting this species than searching for adults. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Ad hoc recording via the national water beetle recording scheme and the Scirtidae recording scheme is probably proportionate for this species, rather than species-specific survey effort. |
| Question 3: | At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages? |
| Response: | N/A |
| Justification: |
