I would just like to add a little here with Joe's video, just one Caprifig can have 400,000-700,000 pollen grains, the average amount of pollen grains a wasp can carry is about 3,000, and only 5-10 grains is needed to set a seed. It seems very little pollen is needed for 1 fig. Another point, his pollen 'grains' are clumps of pollen from the male flowers, these would certainly do better if they were crushed, leaving just dust that would better serve the purpose. These pollen 'grains' will float in the air, and certainly work better.
