Syllepte chalybifascia is a moth in the family Crambidae. It was described by George Hampson in 1896. It is found in India (Nagas).[1]
The wingspan is about 22 mm. The wings are pale glossy and semihyaline (almost glass-like) yellow, the forewings with an ocellate antemedial mark extending from the costa to the inner margin, enclosing a pale centre, its edges rufous and steel blue. There is a steel-blue and rufous wedge-shaped fascia on the inner area from the antemedial mark to the nearly straight black submarginal line, which expands into a spot at the costa and is broken near the inner margin. The discocellulars and veins beyond the cell are marked with rufous and there is a faint diffused rufous line just inside the margin. The apex is blackish, with a white spot below it. The hindwings have a discocellular blackish band and the inner area is tinged with rufous and has three curved black bars on it. There is also a dark submarginal line from the costa to vein 2 with diffused rufous beyond it.[2]
