Distribution Ranging between eastern China south of 33° N, eastern Nepal, and southern Burma, all eight species are vicariant. The genus is also made up of two vicariant lineages, an eastern group comprising two species, and the remaining four species between Nepal, central and southern China, and Thailand (Grehan, 2011).
Systematics Bipectilus was established by Chu and Wang (1985). The genus differs from all other Eurasian and Oriental genera in having bipectinate antennae and from other Hepialidae in its highly specialized male genitalia. Bipectilus may represent a basal lineage within the Hepialidae (Nielsen, 1988).
Habitat Forest. Possiblity of other habitats or variety of forest types is not known.
Biology Larvae of Bipectalis zhejiangensis are reported living in soil and humus where they feed on roots and shoot of forest bamboo and damage is sometimes sufficient for the insect to be regarded as pest species of bamboo (Du et et al., 2011; Wu, 2007).
