Stenoptilodes littoralis is a moth of the Pterophoridae family that is only known from Kauai, Oahu, Molokai and Hawaii, but is thought to be introduced to Hawaii. It is a highly variable species. Adults have two-lobed forewings and three-lobed hindwings, and very long legs. The larvae of ssp. littoralis have been recorded on Geranium cariolinianum australe, while ssp. rhynchophora feeds on Vaccinium species, including Vaccinium penduliflorurn, Vaccinium reticulatum and Vaccinium calycinum. The larvae are green and long and skinny.
