Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | Most accepted records are from Scotland (with only a few from Northern England) Most records from Central and Eastern England discounted as erroneous, due to confusion in separating females from related species. There is a single record of a male from the new Forest in 2018. Northern records in England are prior to 2015. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Habitats are quite generic simply being assessed as a variety of wetlands with no apparent common feature; these include valley bog, seepages, wet birch woodland, exposed riverine sediment and acid upland lochs in Scotland. (Drake, 2018) Targeted actions would seem to be implausible in this instance. |
| 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 |
