Agathiphaga is a genus of moths in the family Agathiphagidae, known as kauri moths. This caddis fly-like lineage of primitive moths was first reported by Lionel Jack Dumbleton in 1952, as a new genus of Micropterigidae. The caterpillars feed only on "kauri" (Agathis) and are currently considered the second most primitive living lineage of moths after Micropterigoidea. The larva has been reported to be able to survive for 12 years in diapause, durability possibly a prerequisite to its possible dispersion around the Pacific islands in the seeds of Agathis.
