Thurberiphaga is a monotypic moth genus of the family Noctuidae erected by Harrison Gray Dyar Jr. in 1920. Its only species, Thurberiphaga diffusa, was first described by William Barnes in 1904.
Thurberiphaga diffusa can be found only in southern Arizona in the United States.[1]
This moth is on wing from July to September.[1]
The caterpillar bores into the stem of the host plant. It is a pinkish color and is covered with rough setae.[1]
Its only host plant is wild cotton (Gossypium thurberi).[2]
