Both the
Ophrys and the book look interesting, Fleur. I don't know the book, but I see that it is available also in English ( it is rather pricey, though, the least expensive one I saw at this website:
http://www.koeltz.com/product.aspx?pid=203155, where you can get it for 79 €).
I have another book on
Ophrys: 'The bee orchids of Greece - the genus
Ophrys' by Zissis Antonopoulos (from Mediterraneo Editions, there is also a Greek version of it), which has lots of very good photos as well. Your
Ophrys looks very much like those described here as
O. tenthredinifera group, which consists of 5 species,
O. dictynnae, leochroma, ulyssea, villosa and
bombyliflora. I don't know how valid these species are, in the book '
Ophrys: The bee orchid of Europe' by H.Æ. Pedersen & N. Faurholdt, they say that 'In our opinion, however, the variation dos not support a systematic (sub)division of the species' (except that they have
O. bomyliflora as a separate species).
