Argillophora furcilla Grote, 1873 - Silver Fork Cane Moth


Taxonomy
Superfamily: Noctuoidea Family: NoctuidaeSubfamily: EustotiinaeP3 Number: 931299.00 MONA Number: 9060.00
Comments: The only member of its genus occurring in North America (Lafontaine and Schmidt, 2010)
Identification
Field Guide Descriptions: Online Photographs: Bamona; BugGuide; MPGTechnical Description, Adults: Grote (1873); Forbes, (1954)                                                                                 
Adult Markings: A medium-small Noctuid. The ground color is clay to buff, with a prominent streak of silver running from the base of the forewing to about a third of the way along the inner margin and from there outward to the cell, where it merges with a small spot with two small points (i.e., the fork). The outward side of the silver streak is shaded with blackish and a similar dark streak runs from the base of the wing to the silver streak near where it ends at the cell. The normal transverse lines are not evident and the orbicular is represented by a small black spot. The hindwings are pale, usually edged with yellow (Grote, 1873; Forbes, 1954). Franclemontia interrogans is another yellowish-brown cane-feeding Noctuid, but is larger than Argillophora and has a hockey-stick shaped white mark in the middle of the wing rather than the long, bent silver streak characteristic of Argillophora.
Wingspan: 24-25 mm (Grote, 1873; Forbes, 1954)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.

Habitats and Life History
Habitats: All of our records come from cane-containing habitats, including peatlands and river floodplains in the Piedmont and Coastal Plain, and dry slopes in the mountains where Hill Cane occurs. No records come from cane growing in savannas and flatwoods that are maintained by frequent fire.
Larval Host Plants: Believed to be stenophagous on Cane (Arundinaria sp.) (Quinter, ), with records coming from both Arundinaria gigantea and Arundinaria appalachiana, but possibly not from Arundinaria tecta, at least where it is associated with fire-maintained habitats
Observation Methods: All of our records come from 15 watt UV light traps

Status in North Carolina
Natural Heritage Program Status: W3
Natural Heritage Program Ranks: G3G4 S2S3->[S3S4]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: Once considered very rare and local (e.g., Forbes, 1954), but now found fairly routinely when cane-containing habitats are sampled during the summer. Even in areas with large amounts of cane, however, only a few individuals have ever been collected in a single trap sample.
