It is hard to conserve them, since each plant does not last long, mostly dying after their first flowering. But the sort of places that you find them most are slightly disturbed areas of rather poor soil (sand or chalk especially), such as by footpaths or in lightly trampled areas, or where the sward is very thin, as the bee orchids cannot compete against the big perennial grasses. But an area grazed by horses often has small bare patches where a hoof has made a dent or hole in the vegetation, and if the grazing pattern you use is continued the bee orchids may well appear for years, but mostly in slightly different places each year.
More interesting than the normal flowers are the frequent mutations that occur. This is because in Britain every flower pollinates itself, as the pollinators (a kind of bee in the Genus Eucera) are very rare in UK, but common in the Med area. Even in the Med area, bee orchids often self-pollinate if a Eucera bee is too late arriving at the plant. The self-pollination means that many mutations occur as there is insufficient variety in the genetic stock so damaged genes often combine and cause a novel plant. Recently a plant was found in my area with no 'bee' at all, but 3 pink sepals, as usual, and another set of identical pink petals, so it looked more like a small lily with 6 simlar 'petals'. Because bee orchids are getting more common, we would expect the number with mutations to increase too, so keep your eyes peeled!
