Extreme…very beautiful pics of pollinator with pollen grains..

You can see pollinia on the head of wasp in last pic.

Those hanging bunch of flowers really look amazing. The flowers have a peculiar shape esp. of the lip and the other two sharp firm and projecting petals. There is some shading even in the white coloured structures. The pink brown bracts are also adding to the beauty. Over and above this is the sharp neat image of a wasp with surprisingly symmetrically attached pollinia.
Very very eye catching pictures.

Potential Pollinator for Pholidota chinensis:
Attaching some pics. Hope you will understand the reasons behind. The closeup reveals something extra if you can check the legs of the insect.

Just for information. When we study pollination biology there is pollination success which can be divided into two parts. Male pollination success: meaning how many times insect visited divided by how many times it was actually able to take off the pollinia.
Female pollination success: meaning how many times insect or pollinator visited the flower divided by how many times it was able to deposit the pollinia on the stigma. Then overall pollination success can be represented by ratio of first by second.

Yes sir, we could see the pollinia in legs. Very informative write-up too. Thanks for sharing.

The white thing on head is the pollinia from Pholidota. Those on feet are probably pollinia of Asclepias.

PLEASE NOTE: THE WHITE THING ON HEAD IS ORCHID POLLINIA. POLLINIA ON THE LEG BELONGS TO UNKNOWN PLANT. THAT WAS THE MAIN REASON FOR SHARING THIS PIC. MOST LIKELY IT LOOKS LIKE POLLINIA OF ASCLEPIAS.
Thanks again for all your compliments. Pollination biology is a very interesting subject and it becomes more interesting once you study this on Orchids !!
