I've been told that in their native growing area (that is, not in the USA), they don't need to be hand pollinated due to the prevalence of some native insects. While pollinating the flowers on my tree, I notice that in almost all the flowers, there are a few black shiny bugs crawling around. These bugs can fly/jump for short distance. They're about 1/16" long. Has any of you cherimoya growers noticed this? I'm not entirely convinced that these guys are pollinators, so I'm still doing it myself.
