Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | Considered to be extinct in England. Only recorded twice from Walberswick (vc 25) in 1956 and 1957. Several subsequent targeted surveys failed to re-find the species. These records seem to represent a short-lived and unsuccessful colonisation attempt. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Extinct in England. Likely never formed an established population. |
| 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: |
