The main event of the moth workshop came after dark. Kyle hung a white sheet with a mercury vapor lamp across an old driveway. Then he painted fermented banana goo onto the trunks of trees along the drive. Until almost midnight, our little group walked from tree to tree to the sheet and back, with stops at patches of blooming milkweed in between. From drab lichen mimics to shimmering green wings; micromoths smaller than a grain of rice to underwing moths the size of my palm; we were captivated by the multitudes of mysterious moths.
