Euthrix

These medium sized lappets are mostly feeding on sedges, grasses and bamboos. The majority of the approximately twenty species occur in the eastern part of Eurasia, with only one species (potatoria) present in Western Europe. The rearing of Euthrix is in general not difficult, but can be very different from one species to another. In general, the warmer their distribution the faster the larvae grow. Colder species like potatoria have overwintering caterpillars. Other species brood nearly continuously in captivity. The caterpillars grow fairly large for the size of the moth.
