O. mammosa was first described by  Desfontaines from Samos in 1807 and its name refers to the prominent basal swellings, literally  meaning "full breasted". It is one of the Eastern Mediterranean's commoner Ophrys, occurring in an almost unbroken distribution from the former Yugoslavia, through Greece and as far as Israel in the East.  In many parts of its range it can be abundant. Most members of the group share similar and easily recognizable characteristics, most notably the bicoloured sepals with their often strongly red tinged lower hemispheres. 

The O. mammosa group is a large and growing one, containing several very similar species whose ranges often overlap and which can be easily confused. In both northern Greece and Cyprus, a good number of     "lookalike" species co-exist and frequently hybridize, forming intermediates which make the already difficult task of species separation even more difficult. Several of the plants depicted here exhibit characteristics which suggest an element of gene ingression and indeed introgression. O. mammosa can be found in several types of habitat from full sun to dappled shade although it always seems to favour a  sheltered position, whether in the lea of a wall or rock, or more usually growing  amongst light scrub or in open woodland. As can be seen from the  photos it can be extremely variable.

This is a robust and handsome orchid which may be as tall as 70cm, containing as many as 15 flowers in a spike. It has a long flowering period and although in most of its range it commences in April, Cyprus populations can appear as early as the end of February. The pictures are from Cyprus, Rhodes and northern Greece, dating from the first week of April in the Aegean and Mid March in Cyprus.
