Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Despite a recent increase in range this species remains confined to two river catchments - the River Wye in Herefordshire and the River Thames from Oxfordshire to London. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | The main threats to this species are river pollution and dredging operations. In addition light pollution is likely to affect this species. |
| 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: | Yes |
| Justification: | This species would benefit from actions to improve water quality and habitat quality, and limit abstraction in watercourses where it occurs. In addition, action to tackle light pollution is required as this species is attracted away from the river by lights. |
