Callophrys xami
Xami Hairstreak, Green Hairstreak, Elfin
Callophrys xami is a small lycaenid butterfly with a wingspan of 2.38–2.86 cm, recognized by the distinctive W-shaped postmedian white line on its yellowish-green hindwing underside. Males defend territories for mating, and the species exhibits complex sexual behavior involving a 'false head' wing pattern that deflects predator attacks. The butterfly is associated with Crassulaceae host plants, particularly Echeveria and Sedum species.
Chrysobothris dudleyaphaga
Chrysobothris dudleyaphaga is a jewel beetle species in the family Buprestidae, described by Westcott in 2007 from California and Baja California. It represents a significant host association discovery, being the first buprestid documented to feed on Dudleya species (Crassulaceae). This finding established that both larval and adult Buprestidae utilize hosts in the Crassulaceae plant family. The species was described with detailed biological notes in its original description.
