Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | Modern records for 20 hectads, many of them recent (Foster et al, 2020). There have been a relatively large number of recent inland records, suggesting that the species is less specialised than previously thought and may have been overlooked for the common H. fenestratus in the past. This suggests its conservation status is likely to be downgraded in a future review. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Refer to Q1 justification |
| 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: |
