I had a dozen italian eggplants this summer. They all flowered beautifully, twice. Bugs never eat from them this season but they never got pollinated! Not one fruit! Just a weird year for pollinators. My herb garden attracts lots of odd pollinators.. You'll see swarms of brightly colored little bees, butterflies, moths or flies that you never see anywhere else. I had a hummingbird moth, that I'd never seen before this season.
