can be distinguished from C. propinquilinea
by the dark coloration in the median area of the forewing. In flavicornis
, with wings folded in resting position, a bar can be noticed joining the am and pm lines across the median area. This is absent in propinquilinea
. Also, the median area of propinquilinea
remains relatively constant in color/shade all the way to the costa, whereas in flavicornis
the median area becomes much lighter in color/shade about halfway to the costa, just before where the orbicular spot is located.
Crumb (1956) described the larva. (3)
