Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | 2003 record from Somerset, otherwise three pre-2000 records, two localised, one not, but considered extinct in England in new draft red list. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Species may be extinct in England. 2003 record needs following up with a targeted survey to see if still present. Targeted action on the ground may be necessary if refound. |
| 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: | No |
| Justification: | This species would not benefit from untargeted management |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Low - Relict or natural rarity |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: |
