Common NameAlfalfa Webworm
SeasonalityLate May to early September.
IdentificationGround color brownish gray. Forewing with veins expanded towards the yellowish buff ST band. There is a faint, yellowish buff ST line on the hindwings. Wingspan 30-34 mm. The genitalia were described by Munroe (1976). Somewhat similar to Loxostege commixtalis but browner, larger, and with FW veins more expanded towards the ST band. Munroe (1976) comments that the "male and female genitalia are not greatly different from those of commixtalis, except blunt cornutus of male generally larger and more broadly spatulate at tip; female with shorter ostial chamber and longer and more pronounced constriction".
