Claremontia alchemillae

This species has a scattering of records from southern England to the Highlands. However, the species was not recognised as British until 2006 and prior to this records would have been identified as Claremontia tenuicornis. Therefore, measures of change cannot be considered reliable until a longer timeframe has elapsed. Previously this taxon has been regarded as a synonym of  Claremontia tenuicornis as was  Claremontia uncta. The three species can be identified by the key in Liston et al, 2006.

 In this species the mesopleura are continuously pubescent. The tegulae are more or less yellow and the pronotal angles are margined with yellow.
