Harmologa sisyrana is a species of moth of the family Tortricidae. This species was first described by Edward Meyrick in 1882. It is endemic to New Zealand and has been observed in the North and South Islands. The larvae of H. sisyrana are leaf rollers and are active, constructing a silken gallery amongst the leaves of their host plant Ozothamnus leptophyllus in order to feed. They feed from New Zealand spring until early summer. The pupa is enclosed in the larval habitat. Adults inhabit open spaces where O. leptophyllus is common and can often be found in sand hills near the coastline. Adults are on the wing from November until May and are attracted to light.
