Identification
Distinguished from similar Chionodes by combination of: black oblique from one-fourth to first discal ; large, irregular black second discal stigma at two-thirds; and whitish zig-zag beyond second discal. The light area from base toward plical stigma and darker region provide additional diagnostic characters. Exact identification may require reference to .
Appearance
Small with wingspan 11–13 mm. whitish to whitish-ochreous, unevenly sprinkled and overlaid with blackish . Light area extends from near base obliquely toward indistinct blackish plical at one-third. Black oblique runs from one-fourth to moderately large black first discal stigma. Second discal stigma black, large, irregular, positioned at two-thirds. area beyond second discal darker, with whitish narrow zig-zag from costa to and lighter spots around margins. light grey basally, darker apically.
Habitat
Oak-associated in western North America. Found in regions supporting its larval oaks: Quercus agrifolia (coast live oak), Q. lobata (valley oak), Q. wislizenii (interior live oak), and Q. dumosa (scrub oak). These encompass coastal, foothill, and interior valley environments.
