Early stages:
Nasu, 1995, describes the chaetotaxy of the larva of Heleanna melanomochla :
SD1 and SD2 on separate pinacula on all abdominal segments except eighth, SD1 and SD2 anteriorly to the spiracle on this segment; D2 setae on shared pinaculum on ninth abdominal segment; L group trisetose; SV group trisetose on first, second, and third abdominal segments, bisetose on seventh, eighth and ninth.
Biology:
Heleanna melanomochla : Larvae feed on the young leaves of mango, folding the apices and margins of the leaves longitudinally. Pupation takes place in the pupal case in a folded leaf.
Distribution:
Heleanna melanomochla occurs in Taiwain; Gates Clarke, 1976, describes several subspecies of Heleanna physalodes from Micronesia.
