Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | GB Red List (Fox et al. 2019): NT. GB long term abundance decline of 97%, though long-term distribution trend is stable and short-term distribution trend shows an increase. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Potentially threatened by Ash dieback (Ash is main foodplant). However, this does not necessitate action soley for this species, rather action is needed for the entire Ash-dependent community. At present the species remains widespread across most of England. |
| 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: | On the basis of current knowledge there is no evidence that these factors would benefit this species. |
