This is one of the Chlorandrena species which is oligolectic on yellow composite flowers (Asteraceae). There are several similar species throughout its range, but there a few key features to look out for. The hind femurs possess a row of small spines, whilst the top of the foveae diverge inwards, away from the eyes. The tergites are also dull and very rough, or ‘shagreened’.
