Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | Confined to England, recent records of this species are known from the Catfield Fen area, Burgh Common and Bure Marshes in Norfolk and the Pevensey Levels in East Sussex. The species used to occur in the New Forest but has not been since there since the 1950s. However, there is no evidence of recent population decline and all known sites are designated and managed for nature conservation. On this basis the species is not considered a priority for recovery actions at the current time. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |

On this basis the species is not considered a priority for recovery actions at the current time. |
| Question 3: | At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages? |
