Ichneutica mutans

Ichneutica mutans, commonly known as the New Zealand cutworm or the grey-brown cutworm, is a moth of the family Noctuidae. This moth endemic to New Zealand and can be found throughout New Zealand, including from Three Kings Islands down to Stewart Island. However this species is not found in the Chatham Islands. The adult moths are on the wing all year round. I. mutans is variable in appearance and can be confused with similar species in the same genus. As a result of the variety of host species consumed by the larvae of the species, including such crops as turnips, wheat and apples, this species is regarded as an agricultural pest. However between the early 1960s and late 1980s the population of I. mutans was shown to have decreased significantly, by over 80%, at two study sites. rdf:langString
