Size
Ferguson (1985) listed the forewing length. (2)
♂ 11-13 mm.
♀ 12.5-15 mm.
Identification
There are two forms described.(4)(2)
Winter-early spring form has a dark costa
Late spring-summer form females have the first five dorsal abdominal segments shaded reddish. The pale yellowish costa is as wide as the fringe of the same color. Wings striated with white.


Grote (1883) original description as Aplodes arizonaria is avaiable online. 125.
Range
Arizona to western Texas (Davis Mountains). (2), (3)
Habitat
Canyons between 4,000-8,000'.(2)
Season
Powell & Opler (2009) reported two flight periods of mid-February to mid-May and mid-June to mid-August. (4)
Food
Ferguson (1985) reported McFarland (1982) reared the species on Quercus L. (oak). (2)
Larvae of the spring generation feed on oak catkins and develop into highly cryptic mimics of catkins.(5)
Life Cycle
These moths differ in appearance and behavior between generations. Larvae of the spring generation feed on oak catkins and develop into highly cryptic mimics of catkins, showing a yellow rugose integument with reddish-brown stamen-like dots. Summer broods feed on oak leaves and have a greenish-grey, less rugose integument.(5)
See Also
Nemoria daedalea is very similar to the early season form of N. arizonaria with the darker costa but has yellow fringe and less distinct transverse lines. (2)
