All male ithomiine butterflies bear androconial "hairs" on the hindwing, which are actually a cluster of highly modified wing scales, erected during courtship displays. Yellow stripes on a black background are a signal to predators that this Napeogenes inachia, as well as nine other co-mimic species that have converged in both wing pattern and forest microhabitat, are unpalatable (see Elias et al., e300).
