Echo Azure
Celastrina echo
Celastrina echo, the echo azure or western azure, is a species of blue in the butterfly family Lycaenidae. Celastrina echo have been observed in mostly western regions of the United States, including California, Oregon, Arizona, New Mexico, and Montana.
The taxonomic division of Celastrina butterflies has been a very complicated issue. Some scientists like Layberry et al. once recognized C. echo as a subspecies of C.ladon (Cramer, 1780) in western Canada. In 2001, Guppy and Shepard nominated C. echo to the species level. Currently, many scientists agree that C.echo is a distinguished species.

Range & habitat
The C. echo larval foodplants are mainly composed of Ceanothus (California wild lilac), Spiraea (Holodiscus), Aesculus (California buckeye), Rubus (blackberries), and some legumes. The adults' host plants are also very diverse. They mostly feed on nectar from plants including the larval host plants listed above, Heteromeles (toyon), Rhamnus, and several others. C. echo are often observed in woodlands, shrublands, and near mountain streams: places that have woody host plants they feed on. Depending on the moisture and relative condition of the larval hostplants, C. echo may fly in 1-2 or more broods from early spring to the fall (around February to late June, July, or even till October if there is no severe cold weather).
