Most plants flower during the day, but some flower at night. One such plant is Datura wrightii, sometimes known as moonflower or Sacred Datura. These plants typically produce many flowers, but each individual flower opens at dusk and typically whithers away early the next day. Researchers have found that the main pollinator for D. wrightii are hawk moths (Family: Sphingidae), which is not surprising given that moths are night-active.
