An eastern Joshua tree (Yucca jaegeriana) inflorescence (flowers) with a Yucca moth (Tegeticula antithetica) trap. SBSC is studying the ecology of the eastern Yucca moth, which is the obligate pollinator of eastern Joshua trees, to determine how climate change affects the emergence of blossoms and eastern Yucca moth visitation.
