Chionodes retiniella
(Barnes & Busck, 1920)
Chionodes retiniella is a small gelechiid first described from western North America in 1920. The is distinguished by its white forewings overlaid with light ocherous , creating a pattern of diffused fasciae. Larvae are known to feed on three species of conifers: ponderosa pine, gray pine, and western hemlock.

Identification
The combination of white forewings with light ocherous overlay and the specific pattern of three transverse fasciae distinguishes this from similar Chionodes. The better defined fascia is particularly useful for identification. The silvery fuscous hindwings contrast with the lighter forewings.
Habitat
Associated with coniferous forests containing trees: Pinus ponderosa (ponderosa pine), Pinus sabiniana (gray pine), and Tsuga heterophylla (western hemlock).
Distribution
Western North America: recorded from British Columbia, Canada, and the United States (Washington, Idaho, Wyoming, Nevada, California, Colorado, New Mexico, Arizona).
Diet
Larvae feed on Pinus ponderosa, Pinus sabiniana, and Tsuga heterophylla. feeding habits unknown.
