Wow then lets prove it right :)....... BTW Ampelocissus flowers are fully open with nectary fully exposed which shines on sunlight. So I think it was enough to attrat insects. I dont remember, but one of my friend showed a very interesting image of antenna of some insect using some equipment. It gives unique bands on the image which is unique for the species too. I assume using the same equipment on this tendril can reveal if it has similar or somewhat similar patterns to attract insects. Will ask him how he did it. Pankaj
