Caenurgina erechtea – Forage Looper

Hodges #   8739

Caterpillar food: alfalfa, clover, grasses, lupines, ragweed  (Bugguide – C. crassiuscula, C. erechtea)

This species is often difficult to tell apart from Caenurgina crassiuscula in photos.  I’ve done my best with my photos.  The following characters can help to differentiate them:

C. crassiuscula is very brown, with a brownish ground color, and lack white edging to the outer margin of the PM blotch-line.
On male C. erechtea the AM line inner boundary is curved outward well before the inner margin.  In C. crassiuscula it is pretty straight.  (Jerry Fauske)
