Species Zanclognatha marcidilinea - Yellowish Zanclognatha - Hodges#8352

8352

see genus page for discussion on Zanclognatha vs. Polypogon classification

Z. jaccusalis now recognized as Z. marcidilinea - see explanation of revision here.

wingspan about 28 mm, based on photos by Jim Vargo at MPG

Adult: forewing medium yellowish-brown; antemedial (AM) and postmedial (PM) lines wavy, jagged, often faint; subterminal (ST) line pale yellow, straight, thick, contrasting sharply against ground color of wing; hindwing a mix of light brown and whitish shading, with conspicuous pale yellow ST line

New Brunswick to Florida, west to Texas, north to Ontario

also recorded in the west from Oregon to British Columbia but I suspect that these "jacchusalis" records now refer to Z. bryanti (see Remarks section below)

Covell's Field Guide (1) gives a flight season of April to July, but Ohio State U. gives a flight season of July to September, with a late date of 23 October

larvae may feed on dead cottonwood leaves (Ohio State U.)

This species appears on the 1998 Macro-moths of British Columbia list by Lafontaine and Troubridge here, but is missing from the 2003 Noctuoidea of Western Canada list (also by Lafontaine and Troubridge) here. I suspect that the name "jacchusalis" has been replaced in the west by Z. bryanti, which is shown as occurring in British Columbia in the U. of Alberta list here.

Wavy-lined Zanclognatha (Z. ochreipennis) forewing subterminal (ST) line is thin and bordered proximally by darker shading, AM and PM lines are usually more noticeable, and fringe is checkered on all wings (compare images of both species at CBIF)

Z. lutalba and protumnusalis lack thick yellow ST line, and Z. obscuripennis has a smooth AM line, not wavy or jagged (compare images of all 4 species at CBIF)

In the west, Z. bryanti has a bicolored forewing with distinctly darker shading beyond the PM line (compare images of both species at CBIF)
