This is an attractive species, though males and females have quite different yellow markings which can be confusing! The yellow 'commas' on the male are often quadrate and frequently merge together. In the female the commas are narrower. In both sexes, the yellow commas extend to the extreme lateral margins of the tergites. See more: https://www.naturespot.org.uk/species...
