The Pinyon Pitch Nodule Moth (''Retinia arizonensis'') is a species of moth of the Tortricidae family. It is found in North America. The wingspan is about 19 mm. Adults are rusty brown. The forewings are mottled with brown, white, and silver scales. There is one generation with a peak flight period in late July and early August The larvae feed on Pinyon pine. They feed on the terminal growth, causing twig dieback. Young larvae first feed on the young needle tissue before tunnelling into shoots. A round nodule of purple-red pitch from which the larvae feed is produced around the feeding site. The larvae are reddish-yellow with a black head. The species overwinters in the larval stage within the pitch nodule.〔(Bug Wood )〕 ==References==
