The Crambidae are commonly known as the Grass Moths.
They, together with the Pyralidae comprise the Pyraloidea, one of the largest superfamilies of Lepidoptera, with more than 17,500 species, worldwide. However, it is considered that many species remain to be described, and this is particularly the case in South-East Asia, where study of these families have been minimal.
Only species identified to at least Genus level are included here at present, the vast majority belong to the subfamily Spilomelinae, with only a few representatives from the other subfamilies.
I would like to put on record the assistance of Roland Breithaupt and Roger Kendrick for the identification of many of these species. Any identification errors are mine.
