The taxonomy of the three species Claremontia tenuicornis, Claremontia alchemillae and Claremontia uncta has not been fully resolved. The three species can be identified by the key in LIston et al, 2006 according to our current understanding. Historic records should be viewed with doubt. In this species the mesopleura are continuously pubescent. The tegulae and the pronotal angles are black.
The larvae are associated with meadowsweet.
Size: Approx. 4 - 6mm
Distribution: England, Scotland, Wales
Flight period: April to August
Plant associations: Filipendula ulmaria (meadowsweet)
