There is something really magical about Joshua trees after nightfall. After all, they are somewhat nocturnal. Because they need to conserve moisture, their leaves respirate in the cooler night air and are dormant during the day, which is the reverse of most trees. Night is when their blooms are most open and fragrant. It is also at night when the Pronuba moth pollinates the flowers of a Joshua tree. So can it be any coincidence that the trees seem to dance in the moonlight?
