Ectoedemia spiraeae

Description

Ectoedemia spiraeae is a moth of the Nepticulidae family. It is only known from Slovakia and the Mátra mountains in Hungary. The wingspan is 4.8-5.6 mm. Adults have been reared from February to March and from May to June. There is probably one generation per year. The larvae feed on Spiraea media. They mine the leaves of their host plant. The mine consists of a corridor following a vein, occasionally the leaf margin, filled with brown, dispersed frass. The corridor widens into a large, irregular blotch with blackish dispersed frass. -
