Description
Sparganothoides hydeana is a small moth in the tortricid family. Adults have a wingspan ranging from approximately 16 to 20 mm. The forewings are generally mottled brown and gray with subtle darker markings, while the hindwings are a lighter grayish hue. Detailed morphological characters, such as genitalia structure, are used to differentiate this species from closely related members of the genus.
Distribution and Habitat
The species is known from the southwestern United States, primarily Arizona, and from adjacent regions of northern Mexico (e.g., Sonora). It inhabits arid and semi‑arid environments, including scrubland and oak‑dominated woodlands where host plants are present.
Biology and Ecology
Adults are typically on the wing during the warmer months, with flight records concentrated in late spring through early summer. Larval host plants have not been comprehensively documented; however, members of the genus Sparganothoides are generally associated with a variety of woody angiosperms, including species of Quercus (oak) and Juniperus (juniper).
Taxonomic History
The species was originally described by Lord Walsingham in 1913 under the name Tortrix hydeana. Subsequent taxonomic revisions placed it in the genus Sparganothoides, a group established to accommodate certain North American tortricid moths with distinct genitalic features.

Notes
Information on the larval host range, precise phenology, and detailed distribution beyond the regions noted above remains limited. Further field studies and specimen examinations are required to clarify these aspects of the species’ biology.
