Despite
its name, O. lesbis is not endemic to Lesbos and may
be found on the neighbouring island of Samos as well as the Bodrum peninsula in southwest Anatolia. It is
however a true rarity in all its stations and is perhaps at its most
frequent in the Andisa area of northwest Lesbos ( where all these photo's were taken ).
It
grows in sometimes substantial colonies on alkaline soils in full sun
to mid shade but seems to demonstrate a preference for moist substrates
with light tree covering. This may be open oak woodland or
as with the illustrations here, mixed pine, which is why the flowers
show a liberal dusting of pollen. This pine pollen is a
familiar problem with orchid photography in the Aegean and on
occasion's can encrust the flower so thoroughly that it renders an Ophrys indistinguishable. The only tip in this respect is to identify
buds that are about to open and catch them first thing in the morning.
This isn't particularly practical however when you find that rarity
miles from base !
O. lesbis is a member of the O. argolica group that grows to a maximum of 30cms and may contain up to 10
flowers, though more normally it would be a fairly low, sturdy plant
with around 6. It can be variable in appearance and in the case of the
colony shown here will readily hybridise with other Ophrys. A single recognizable plant of O. villosa was growing amongst the colony
and many of the nearby O. lesbis showed marked characteristics of the
interloper. Pictures 11, 12 and 13 are all hybrids but the
influence of O. villosa on No 12 is especially recognizable.
The photo's all date from the second week of April.
