Explanation of Names
HAHNCAPPSIA: named in 1976 by Murnroe in honor of Hahn William Capps, a USDA entomologist from 1938-64 who described 7 species in this genus
14 species in our area(1):
H. alpinensis Capps, 1967 (2)
H. cochisensis Capps, 1967 (2)
H. coloradensis Grote & Robinson, 1867
H. fordi Capps, 1967 (2)
H. huachucalis Capps, 1967 (2)
H. jaralis Schaus, 1920
H. mancalis Lederer, 1863
H. marculenta Grote & Robinson, 1867
H. mellinialis Druce, 1899
H. neobliteralis Capps, 1967 (2)
H. neomarculenta Capps, 1967 (2)
H. pergilvalis Hulst, 1886
H. pseudobliteralis Capps, 1967 (2)
H. ramsdenalis Schaus, 1920
wingspan 18-24 mm, based on photos by Jim Vargo at MPG
Adult: forewing color varies by species from white to dull yellow to orangish-brown; AM and PM lines wavy and irregular, the PM line usually with a few small teeth; subterminal line fairly straight, diffuse and somewhat blurred, varying from distinct to almost invisible; hindwing semitransparent in basal two-thirds, becoming more opaque in distal third; upper two-thirds with fairly straight PM and ST lines in several species (lines do not reach inner margin, but may appear to do so in living moths at rest with lower third of hindwing folded under); H. coloradensis may have no noticeable lines on hindwing
most of United States and southern Canada, south through Mexico to Costa Rica; one tropical species occurs south to Bolivia
adults fly in July and August
depending on species, larvae may feed on dock (Rumex), goldenrod, mint, morning glory, pigweed (Amaranthus), ragweed (Ambrosia), and tobacco; reports of H. pergilvalis feeding on corn are questionable
See Also
adults of a number of other genera are similar but lack one or more of the following characters: fairly straight ST line on forewing; toothed PM line on forewing; straight lines on hindwing (compare images of numerous other genera by Jim Vargo at MPG)
