Glyphipterix semiflavana

Glyphipterix semiflavana is a species of sedge moth in the genus Glyphipterix. It was described by Issiki in 1930. It is found in China and Japan.

Adults are 4–5 mm long and greyish-brown in colour. There is one generation per year.

The larvae feed on Phyllostachys species. They mine the leaves of their host plant. They first mine into the main vein of newly sprouted leaves, causing wilting of the damaged leaves. When they reach the terminal end of the vein, they vacate the mine and move to another leaf. Larvae are light-green and reach a length of 7–10 mm.
