Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | GB Red List (Fox et al. 2019): NT. Confined as a breeding species to circa 10 sites. Sole larval foodplant is nationally scarce and NT. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Dependent on a single, declining host plant (Nottingham Catchfly) which requires appropriate habitat management to maintain populations. No recent information available for condition of populations on calcareous grassland sites. |
| 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: | Larval foodplant requires specific conditions which will not be achieved by 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 |
