Gazoryctra sciophanes
(Ferguson, 1979)
Gazoryctra sciophanes is a hepialid described by Ferguson in 1979. It belongs to a of 10 North American distributed from Alaska to the southern Appalachians and southern Rocky Mountains. The species has a wingspan of approximately 35–38 mm. Its range includes North Carolina and Tennessee, with the genus notably absent from much of the southern-central United States despite apparently suitable forested .

Identification
Distinguished from congeneric by morphological features detailed in Ferguson (1979). Gazoryctra confusus is a similar species with which it has been directly compared; accurate identification requires examination of genitalia and other structural characters. The southern Appalachian distribution helps separate it from northern Gazoryctra species.
Appearance
Wingspan approximately 35–38 mm. As a member of Hepialidae, likely have reduced mouthparts and relatively broad wings. Specific coloration and pattern details are not documented in available sources.
Habitat
Forested regions. The occurs in forested where larvae are believed to feed below ground.
Distribution
United States: documented from North Carolina and Tennessee. The Gazoryctra ranges from Alaska to the southern Appalachians and southern Rocky Mountains. The is absent from much of the southern-central United States, a distribution pattern hypothesized to reflect historical biogeographic barriers rather than current suitability.
Diet
Larvae are believed to feed on roots or other organic matter in soil, based on observations of the .
Life Cycle
As with other Hepialidae, larvae likely live in soil or decaying wood and feed on plant roots or detritus. probably do not feed. Specific developmental timing and number of instars are not documented.
Ecological Role
Larvae may contribute to soil nutrient cycling through root feeding and processing of organic matter. Specific functions are not quantified.

Historical biogeography
The absence of Gazoryctra from much of the southern-central United States, despite ostensibly suitable forested , has been attributed to lack of following regression of inland seas that covered this region until the end of the Mesozoic era.
