Dichromodes ida (also known as the blue and orange rock looper) is a moth of the family Geometridae. This species was first described by George Hudson in 1905. It is endemic to New Zealand and is found in Central Otago. This species inhabits open rocky places at altitudes between 100m to 900m. The larvae of D. ida are cryptic in appearance and feed on lichens growing on rocks. They appear to pupate in rock clefts, forming a chamber made of moss and silk. Adults are day flying and are on the wing from October until December.
