The ilima leaf miner (Philodoria marginestrigata) is a moth of the Gracillariidae family. It is endemic to the Hawaiian islands of Nihoa, Kauai, Oahu, Molokai and Hawaii.

The larvae feed on Dubautia species, Xanthium echinatum, Xanthium strumarium, Abutilon species (including Abutilon grandifolium, Abutilon incanum and Abutilon molle), Sida species (Sida cordifolia, Sida fallax, Sida meyeniana and Sida rhombifolia) and Datura species. They mine the leaves of their host plant. There may be as many as twelve mines in a single leaf, and the cocoon is made within the mine.
