That is what appears to be happening Har.
Have seen low to decent fruit set with the ants around, and no help from me. If they do pollinate, they're not that great at it.
Much better fruit production and size with hand pollination.
Was checking flowers last night. 2 flowers were open, with an opening just big enough to fit the tip of a chopstick in it. Thinking they were female, I went to pollinate them. A ton of fresh pollen fell out, so instead just decided to collect the fresh pollen. Other flowers were barely opening in the middle, no pollen falling from them, so pollinated them.
My point is there is very little difference in outside appearance between a male and female flower. You probably have one plus day of a receptive female flower, that then turns male and has viable pollen for a day plus. Trying to catch them before the petals fall off, think that is a better strategy.
Found this today:
