Species Feltia jaculifera - Dingy Cutworm Moth - Hodges#10670

10670

Dingy Cutworm (larva)

Feltia ducens - and three other old synonyms listed at All-Leps

The common name "Bent-line Dart" is erroneously applied to this species by some sources. It is actually the common name for Choephora fungorum.

common to abundant

wingspan 30-40 mm

Adult: forewing dark gray to blackish, patterned with white, gray, and tan streaks and lines; two white-lined veins (M3 and CU1) extend from bottom corner of reniform spot nearly to outer margin, forming a distinct W shape where they meet subterminal line; orbicular spot broadly triangular, adjoining whitish strip running parallel to costa from base to top edge of reniform spot; claviform spot dark gray, elongate, extending to level of reniform spot; reniform spot yellowish to light brown, with paler outline; dark gray patch along costa near apex, and another dark patch along outer margin near apex; hindwing dirty white with dark gray discal lunule, veins, and terminal band in male, or uniformly brownish-gray in female; fringe pale yellowish

Larva: body light grayish dorsally with smooth skin; four black equal-sized dots on dorsal surface of each abdominal segment; ventral surface pale yellowish

coast to coast in North America (except Arizona, southern California, and Newfoundland), north to Northwest Territories, Yukon, and Alaska

fields, gardens, open spaces, waste places; adults are nocturnal and come to light

Adults fly in the fall; on Block Island, RI, adults fly mainly in September but have been recorded throughout August and October as well.(1)

larvae present in fall and spring (they overwinter)

larvae are generalist feeders on more than 40 species of plants, including alfalfa, aster, blueberry, chickweed, clover, corn, dock, flax, goldenrod, garden vegetables, grasses, mullein, oats, plantain, raspberry, rye, tobacco, wheat

one generation per year; eggs laid in fall; overwinters as a partly-grown larva

The larva (cutworm) may be "dingy," but the adult is the brightest and boldest-patterned eastern species of Feltia. A more appropriate name for the adult might be Bright-striped Dart.

three other Feltia species are similar (herilis, subgothica, tricosa) but all lack the two whitish veins extending from lower corner of reniform spot, and forming a sharp W shape in subterminal line

Master's Dart (F. herilis) is darker along the inner margin of the forewings.

Subgothic Dart (F. subgothica) is very similar but has a distinctly shorter claviform spot.

Tricose Dart (F. tricosa) is very similar but has a distinctly shorter claviform spot.

Black Cutworms (larvae of Agrotis ipsilon) also have four black spots on dorsum of each abdominal segment, but the inner pair of dots are about half the size of the outer pair (compare images of both larval species at Iowa State)
