General Description
The Leucania phragmitidicola wingspan is about 32 mm. The forewing is light tan but not uniformly-colored. There is an indistinct and diffuse pale band that runs obliquely from the apex to the inner margin. The pale band is surrounded on both sides by slightly darker shading. The antemedian line is composed of several dark but inconspicuous dots. The main vein runs from the base to middle of wing. The main vein is whitish, bordered by a thick dark line on inner edge, and has slightly darker shading along the outer margin. The hindwing is white with no dark border (Powell and Opler, 2009).

L. phragmitidicola adults fly from June to October (Powell and Opler, 2009).

Range Comments
