Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | Known in the modern period from just a single individual seen at Box Hill, Surrey in 1983. Formerly more widespread with records for 8 hectads from high quality chalk grassland sites in southern England, it clearly underwent a substantial decline during the 20th century and there is no reason to think this is not continuing and that it is probably already extinct in Britain. It is a very distinctive species and its last recorded site continues to be relatively well-worked by entomologists. On this basis, it is probably not a suitable candidate for recovery actions. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |

| 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 |
