About Eacles oslari Rothschild, 1907
Eacles oslari, commonly known as Oslar's eacles, is a moth belonging to the family Saturniidae. This species can be found starting from the Santa Rita, Patagonia, Atascosa and Huachuca mountains of southern Arizona, extending south into the Mexican states of Sonora, Sinaloa and Chihuahua. The wing color of Eacles oslari varies from yellow to purple brown. The species was first formally described in 1907 by Walter Rothschild and Ernest J. Oslar. Oslar served as the first entomology curator for the Colorado Museum of Natural History, which is now known as the Denver Museum of Nature & Science. Rothschild employed Oslar to collect moth specimens, and this species was eventually named in Oslar's honor. The wingspan of adult Oslar's eacles ranges from 112 to 146 mm. Adult moths are active on the wing from July to August. This species is vulnerable to predation by bats. The larvae of Eacles oslari feed on Quercus oblongifolia, Quercus emoryi and Sapindus saponaria drummondii.
