Status and Distribution
Adventive that may have established itself temporarily in Essex (in 1971) and occured once in Worcestershire (in 1978). A further, unconfirmed, record (in 2004) came from close to the original Essex site but enquiries failed to produce a specimen or further conclusive evidence. Possibly no longer present in the British Isles.
Three records from adjacent areas in Glamorganshire (c1979) have come to light but no specimen or other evidence suggesting the records may be credible have been found.
