Cricula ceylonica

Cricula ceylonica, the Sri Lankan cricula silkmoth, is a moth of the family Saturniidae. The species was first described by Karl Jordan in 1909 and it is endemic to Sri Lanka. The debate of this species with much broader range circular species - Cricula trifenestrata is not yet fully understood. However, Rougerie et al., in 2009 considered Cricula ceylonica a valid species, probably endemic to Sri Lanka.

Taxonomy
Very similar to C. trifenestrata, therefore many texts and agricultural publications still classified the Sri Lankan population under C. trifenestrata as its subspecies, C. trifenestrata ceylonica. The revision of the two species needs more clarifications and researches.
