The White Tangle Fern Moth was described in 1862, it is an Indo-pacific species that occurs in parts of Africa to Asia and Australia well into eastern Polynesia.

There are several synonyms that formerly were thought to constitute distinct species and subspecies, some of which were believed to be endemic to single islands or island groups.

The species reaches a wingspan of 2,7 to about 3 cm.

The caterpilars feed on several endemic, native or even introduced fern species including Adiantum, Asplenium, Lygodium, Microsorum, Nephrolepis and Pellaea spp.. [1][2]


The species is also known from the Hawaiian Islands, but is very likely not native to these islands.
