Ectoedemia ortiva is a moth of the Nepticulidae family. It is found in the Russian Far East (Primorskiy Kray). The habitat consists of dense, mostly deciduous forests. The wingspan is about 5.6 mm. The forewings are grey-brown, with a distinct bronze lustre. The hindwings are fuscous or grey-brown. Adults are on wing in July. The larvae possibly feed on Quercus species and probably mine the leaves of their host plant.
