 The southeastern subspecies of N. bifilata has a very distinctive white stripe on the dorsal surface of the abdomen. Note the presence of a red terminal line similar to N. bistriaria and N. lixaria, but less obvious checkering of wing fringe. The abdominal stripe distinguishes it from the aforementioned two species in the East. White postmedial lines on wings are thinner, fainter and noticeably less pronounced than those of N. bistriaria. Nemoria bifilata has a cool season spring brown adult in a form similar to that of Nemoria bistriaria (see below left). An eastern Texas subspecies Nemoria bifilata planuscula has white spots rather than a stripe on the abdomen (below at right). For images of larvae of Texas N. bifilata planuscula, click here.
