''Agathymus neumoegeni'' is commonly referred to as the Orange Giant-Skipper but has also been christened Neumogen’s Giant-Skipper, Neumogen’s Agave Borer, Neumogen’s Moth-Skipper, and Tawny Giant-Skipper. == Physical characteristics ==
This butterfly is typified by its orange upf spots. The upper side of its wings are an orange to yellowish-orange color with black margins and black patches. The underside of the hind wings are colored a darker shade of gray and marked by a pale shaded band. Also found on the underside of the wings are two indistinct white spots along its upper boundaries.〔Opler, Paul A., and James W. Tilden. "A Field Guide to Western Butterflies". New York: Harcourt, 1999〕 However, there are small discrepancies between the female and male genders of the Orange-Giant Skippers. The males have orange spots that form a band on both the forewing and the hind wing. The outside portion of spot seven overlies the interior edge of spot six on its forewing. In females, the orange band is thicker and the inner end of spot nine on its forewing is pointed. Both genders have a wingspan that ranges from 1.75 to 2.375 inches. The caterpillar form of the Orange Giant-Skipper has a body that is usually a greenish or bluish-white color with a dark brown head〔Allen, Thomas J., et al. Caterpillars in the Field and Garden: A Field Guide to the Butterfly Caterpillars of North America. New York: Oxford UP, 2005. .〕 Different from “true butterflies”, skippers rest with their forewings open at a forty-five degree angle and hind wings horizontal. Skippers are grouped together in part because of their swiftly direct and vigorous flight patterns. The butterfly deemed the Arizona Giant-Skipper (Agathymus aryxna) is sometimes confused with the Orange Giant-Skipper due to their similar post median bands and coloring. However, the Orange Giant-Skipper is typically distinguishable by its broader bands and its abundant orange coloring.〔Brock, James P., Jim P. Brock, and Ken Kaufman 360〕 Also, the Arizona Giant-Skipper has fringes that are almost always checked white and black while the Orange Giant-Skipper’s fringes are usually no more than black.
