Euchloe lotta, the desert marble, is a species of butterfly that occurs in the interior of British Columbia, Canada.[1]
It is mostly white with black markings on the topside of the forewing tips and body. The underside has greenish-grey veins especially in the hindwing. The wingspan is from 38 to 40 mm.[1]
The desert marble's flight season in North America is from April to May.[1] It inhabits sagelands, deserts, juniper woodland, dry, rocky areas, dry ravines, and canyon walls.[2]
Larvae feed on Arabis furcata, Arabis sparsiflora, Arabis bolboellii, and Halimolobos whitedi.[3]
