Description

Wiseana umbraculata, also known as the bog porina, is a species of moth belonging to the family Hepialidae. It was described by Achille Guenée in 1868 under the name Pielus umbraculatus from specimens collected by Richard William Fereday. This species is endemic to New Zealand. It was regarded as being common in Whanganui in the early twentieth century. The wingspan is 38–50 mm for males and 49–66 mm for females. Forewing colour varies, but is usually fawn, pinkish fawn or infuscate. The hindwings are pinkish-fawn to yellow-fawn. Adults are on wing from September to April. Food plants for the larvae include species of grass. The larvae of W. umbraculatus are regarded as a major pasture pest.
