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 pubescence on the mesopleura has a completely glabrous zone separating it from the scattered hairs of the mesosternum. The tegulae are yellow and the pronotal angles are black.
The larvae feed on meadowsweet and lady's mantle.
Size: Approx. 4.5 - 5mm
Distribution: England, Scotland, Ireland
Flight period: April to August
Plant associations: Filipendula ulmaria and Alchemilla vulgaris (meadowsweet and lady's mantle)
