Excellent Shots…….nice use of jeep

Very good study …. Identifying a pollinator of a particular species must be a tedious job with great patience. I do not know whether this hoverfly is generalist or specific to this orchid (egg laying though indicate specific relationship) this case is very similar to the co-evolution of Yucca whiplei and Pronuba yuccasela case.
Pollination methods are very interesting in flowering plants and the plants are more evolving taxa for such relationships. This case gives me another example to be explained to PG students for co-evolution.

Thanks a lot sir.
Hoverflies are not generalists in case of orchids, but they do lay eggs in flowers of other non-orchidaceous plants.

This terrestrial orchid was shot from a grassy slope near Mussoorie during our recent visit…
as learnt during Orchidaceae episode, I suppose this is an Epipactis sp… please help to provide exact id…

Epipactis veratrifolia.

Epipactis veratrifolia
Eastern Marsh Helleborine
Family – Orchidaceae
This beautiful Orchid is highly specific in habitat and is found near marshy habitat . Recently I found good population (more than 60 plants) of this beautiful Orchid growing near the local ravines along the edges of wheat field .
Associated species includes Vicia sativa, Gentiana pedicellata, Medicago polymorpha and Saccharum sp.
Photographed at Hamirpur, Himachal Pradesh
Altitude – 750metres
Dated – 10/3/2018

Very pretty. You can see an egg or caterpillar in the fourth pic. I described a new mode of pollination Vermiculiphily. 

Very beautiful presentation …, always nice to see such beauties in nature..  

Thanks … You really have very keen observation, Thanks for letting me know about this different mode of pollination, I recently came across your paper on VERMICULIPHILY in Orchids.
