Glyphodes negatalis, the karanj defoliator, is a species of moth of the family Crambidae. The species was first described by Francis Walker in 1859. It has a wide range in the tropics, including South Africa, The Gambia, Mali, India, Sri Lanka, Hong Kong, Japan and eastern Australia (including New South Wales and Queensland).
The wingspan is about 20 mm. Adults are white with several ragged pale brown submarginal bands outlined in dark brown. The hindwings are white with brown veins and brown margins.
The larvae feed on Dillenia indica, Ficus microcarpa and Ficus religiosa (Moraceae). In India they had been found also as a main defoliator of Pongamia pinnata (karanj) and in Japan the larvae had been found on Ficus superba var. japonica.
