Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Confined to southern England, where it is associated with early-successional, and often ephemeral, habitats on dry calcareous grassland and open ground on chalky soils. It is very local but may be abundant where found. The data indicate a recent decline for this species and it is known from fewer than 15 hectads during the modern period, but is designated Nationally Scarce in the expectation that it is likely to occur more widely. At a landscape scale, it is a species that would benefit from untargeted habitat management to increase early successional habitat mosaics. At the current time it is not a priority for recovery actions.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Could do with status assessment update
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
Justification:
