Biology and notes. Copestylum escomeli is associated with coastal desert flora from the Coastal Desert province (Morrone 2014). The species is found in shrublands at high-altitude (Arroyo et al., 1982), and in desert bloom events. It has been associated with shrublands and flowers of H. stenophyllum (César Martínez and Gamal Naser, CSP records); Frankenia chilensis K. Presl (Rodrigo Barahona-Segovia pers. obs.); Balbisia peduncularis (Lindl.) D.Don (Gabriela Germain, CSP record); Nolana crassulifolia Poepp. (Rodrigo Barahona pers. obs.); Carica chilensis (Planch. ex A. DC.) Solms (Ana Sandoval, CSP record); Cistanthe sp., Tetragonia maritima Barnéoud and Encelia canescens Lam. in the coastal desert (R. Barahona-Segovia, pers. obs.). This species also inhabits the sclerophyllous forests of Mediterranean Central Chile.
Conservation status. LC; EOO = 209,948 km 2, AOO = 100 km 2, 22 subpopulations and 23 localities.
