Amphipoea americanaAmphipoea americana
Taxonomy
Superfamily: Noctuoidea Family: NoctuidaeSubfamily: NoctuinaeTribe: ApameiniP3 Number: 932447 MONA Number: 9457.00
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: Very similar in color and markings to Amphipoea interoceanica, but is larger and not as stocky (Forbes, 1954).
Wingspan: 30-35 mm (Forbes, 1954)
Forewing Length: 16 mm (J.B. Sullivan, pers. obs.)
Adult Structural Features: Males are best distinguished by the length and shape of the digitus: "long, pointed, projecting far beyond the lower edge of valve" in americana but "short, obliquely truncate, not projecting beyond edge of valve" in A. interoceanica (described and illustrated by Forbes, 1954). The antennae are somewhat serrate in the males, with the serrations longer in americana than in A. interoceanica (J.B. Sullivan, pers. obs.).
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].

Habitats and Life History
Habitats: Our records come mainly from high elevation forests and semi-natural grasslands, but also from wet meadows and bogs. One isolated Piedmont record comes from a residential area adjacent to both fields and bottomlands.
Larval Host Plants: Larvae reportedly feed on sedges and grasses, including corn, but have also been recorded on iris (Wagner et al., 2011). We do not have any feeding records in North Carolina. - View
