Eumetriochroa hederae

Description

Eumetriochroa hederae is a moth of the family Gracillariidae. It is known from the islands of Honshū, Kyūshū, Shikoku in Japan and in China (Hunan, Jiangxi). The wingspan is 8.1-9.7 mm. The larvae feed on Hedera rhombea and Hedera nepalensis var. sinensis. They mine the leaves of their host plant. The mine starts as a small irregular blotch, occurring on the upper side of the leaf. It is purple brown in colour. After hibernation, the larva creates a very long serpentine mine, which is stretched from the blotchy part. Most larvae make a pupal chamber at the end of the mine. The pupal chamber is elliptical, with a swollen under side and wrinkled upper side.
