This clearly indicates that the specimen is of L. dorsalis which is important as it is the first time it has been found in Nottinghamshire, and is nationally scarce in the UK (Notable B). It is mainly found on calcareous or sandy soils, is associated with ragworts (Senecio), and has become scarce due to the loss of its habitats (conversion of grassland to agriculture, infilling of quarries, habitat succession such as in once-open woodland rides and clearings, grassland 'improvement' through fertiliser application, herbicide use and woodland clearance). Open conditions with ragwort are required and conservation measures can be straightforward e.g. retaining some open areas in woodland through rotational cutting, or grazing is some other situations (Hyman, 1992). So, it's good to see this species in a previously unrecorded location, especially as several individuals were seen with just one sent to me for identification.
