Dibusa
microcaddisfly
Dibusa is a genus of microcaddisflies in the family Hydroptilidae, established by Ross in 1939. The genus is monotypic, containing a single described species, Dibusa angata. This species exhibits a highly specialized ecological relationship, being obligately associated with the freshwater red alga Lemanea australis throughout its larval development. The genus represents a narrow example of host-specific adaptation within the diverse microcaddisfly fauna.
