For example, the pollinator of Mojave yucca ( Y. schidigera ) in the Mojave Desert and Y. filamentosa in Missouri is a white moth named T. yuccasella , while the pollinator of joshua trees ( Y. brevifolia ) is a dark gray moth named T. paradoxa . The moth (Tegeticula antithetica) is the tree’s exclusive pollinator, and the tree (Yucca jaegeriana) is the moth’s only host, producing the seeds eaten by its larvae. Early 16th century; earliest use found in Gavin Douglas (c1476–1522), poet and bishop of Dunkeld. The moth then flies in circles until it catches the scent of the flower.
