I can't say that this is the best picture I have taken, but just wanted to share to emphasize the importance of study on Plant-Pollinator interactions.
Bulbophyllum is one of the largest genera of epiphytic orchids which are very widespread and at the same time have a very peculiar mode of pollination by insects. The floral morphology is very diverse and so is the odour which can be drastically bad as a rotten fish or as good as fragrance of rose+vanilla. They dont have spur but the labellum and other part of flowers have glands that secretes some compounds which attracts insects. They even secrete chemicals on the labellum to attract insects. You may like to read this to understand more: http://aob.oxfordjournals.org/content/93/5/499.full.pdf The pic is one of such potential pollinators on a species, Bulbophyllum lasiochilum Parish & Rchb.f.. This is the yellow form of the species Implications: Plant-Pollinator study becomes very important for any species which is assume to be rare and their existence is threatened. If the pollinator is missing then even if the plants have no other threat, they wont survive for long. A pollinator is must for maintaining the genetic diversity within a species, in natural condition. Unfortunately such studies are lacking in India and hence there is an immense need to undertake such studies so as to design proper conservation management plans for important plant species.
