Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: CR, criteria: B2ab(ii,iii,iv): status unchanged, with no records since 1985. Only recorded from 3 hectads in S England.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Not recorded since 1985 despite many apparently suitable sites
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

Species Assessment

Current step on the Species Recovery Curve (SRC): 2. Biological status assessment exists
Recovery potential/expectation: Low - Relict or natural rarity
National Monitoring Resource: Opportunistic - sufficient
Species Comments: Found among stones on a (now destroyed) quarry floor in Somerset and in damp grassland (IoW). On the continent it occurs in a wide range of habitats including tussocky grassland.
