Ophrys blitopertha
 

This Ophrys is the title species in a group that boasts just three members,  itself O. blitopertha, its very  similar relative O. persephonae and the newly recognized O. urteae from Turkey.  It was first described   from the Cyclades by Paulus in 1998 and its name refers to the scarab beetle which serves as its pollinator,  Blitopertha lineolata. Interestingly this is one of the very few Ophrys species that does not have a bee as its  pollinator.

O. blitopertha and O. persephonae are very alike and both find a home in the eastern Aegean, although the  former is rather more widespread in a range that takes it from the Cyclades, through the Aegean basin into  Anatolia. There is a significant overlap of range with its fellow group member and given the similarity of the  two species, there is considerable scope for confusion.

Differentiation can be difficult and the first distinguishing feature to look for is not the flower itself but  the overall plant and its habitat.  O. blitopertha is slender (often weedy) with few flowers and will be  growing in a full sun position. Picture 6 is hardly a classic photograph but depicts very well its "jizz" and the  characteristic situation in which the species thrives.  O. persephonae on the other hand will rarely (if ever)  tolerate such an open, arid position and is usually to be found in open pinewoods or shady verges. It is a  robust orchid of 30-40cm with up to 10  individual flowers.

As can be seen from the illustrations O. blitopertha can be variable and on the island of Chios in particular  there is a variation with a vivid orange lip margin (see photo's 7, 10 and 11)

The photographs are from Chios and Lesbos dating from the middle of April.
