Heterocrossa eriphylla (Meyrick, 1888). Endemic. Uncommon.
This lichen mimic is a scarce moth inhabiting native forests throughout the north island. They rest on tree-trunks by day and can be attracted to artificial light during most months of the year.
The larva feeds on the callus tissue around wounds or plant galls caused by other insects in various situations, e.g. on the inner bark of beech, or in side-tunnels made by larvae of the Puriri Moth in wineberry. Pupation is in the feeding place.
This is the largest species in its genus; other Heterocrossa are similarly patterned on a pale brownish, white or grey or blackish background, and have larvae that feed on fruits and seeds (Hoare, 2014).
