Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | The last record of this species is from 1939 where 31 individuals were reported from Abbey Wood in Kent, no further records exist of the species although it is fairly simple to identify. This implies that its population has died out and that it is unlikely that further populations exist. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | The adults are recorded from gardens and as flower visitors, this makes any targeted actions, should any individuals be found difficult at best. No specific habitat requirements are known beyond this. |
| 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 |
