Tineids are unusual among Lepidoptera as the larvae of only a very small number of species feed on living plants, the majority feeding on fungi, lichens, and detritus.

Through the use of radiation mutation to create new varieties of barley and rice, and the active involvement of Peruvian farmers in the breeding process, agricultural productivity and income have increased.

That applies even to the numerous new plant varieties that have resulted from wide crosses, hybridizations that move genes from one species or genus to another across what used to be considered natural breeding boundaries.
