Nemoria festaria (Hulst, 1886). 
Nemoria festaria is a southwestern species characterized by particularly thin white am and pm lines on a finely striated green wing. A red terminal line is present and the fringes are commonly checkered with red-pink markings at the end of each vein. The Arizona specimens pictured here both show the presence of a well developed white abdominal spot on the A2 segment, with the resulting pattern of 4 or 5 contiguous abdominal spots. This is in contrast to the pattern on many other Nemoria species such as Nemoria obliqua where the spot is missing or only very weakly developed on the second abdominal segment. Ferguson (1985) reports that the second abdominal segment spot is frequently present in Arizona specimens but may be missing from Texas specimens.

A female Nemoria specimen from Oklahoma in the collection of the USNM with pale yellow fringes, a strong red terminal line, white striations on the wing and very thin, almost obsolescent am and pm lines is almost certainly festaria with four white spots on the dorsal surface of the abdomen. The specimen is in excellent condition. The Oklahoma moth species list records Nemoria festaria from McIntosh, Payne and Roger Mills counties. The USNM specimen adds a Sequoyah County record and raises the possibility of the species occurring in neighboring Arkansas. For images of Nemoria festaria eggs, larvae and pupa, click here.
