Adults eclose, usually within three weeks.


Females call in the males with a pheromone released from a gland at the tip of the abdomen.

I am not sure if the following characters are consistent or even relevant, but differences between N. alophus and N. furtadoi which are sympatric is some areas (San Lorenzo, Central, Paraguay) include the following:
N. furtadoi has a) more pronounced/produced scalloping of the forewing outer margin; b) less dentate fw pm lines; C) a more upright white bar extending from the inner margin near the anal angle, only about a third of the way up the wing; D) a lighter, more even ground colour to the forewing; and E) a larger, rounder black fw cell marking, with a smaller accessory black mark just below the costa.

In N. alophus the white bar is more oblique and extends all the way up to the inside of the cell mark, which tends to be thin more linear/streak-like) with a greatly reduced secondary mark.
