         The vernacular name of the Blue Mason Bee Osmia caerulescens may appear to be fanciful unless the small and very chunky female is examined from more than one angle. As will be evident from the photographs there is only a faint blue tinge on the abdomen visible in the third photograph and the overall appearance is usually that of an entirely black bee. Females are relatively straightforward to identify as their heads are relatively large but the males are far less straightforward as there are two other species that appear to be very similar, they are all very small and their appearance can differ considerably with age once the hairs have been worn away. These will need to be separated using appropriate references or by association with the females of the same species.
