Lepidoptera emerged from nests of the Bull-headed Shrike, Lanius bucephalus Temminck and Schlegel, in Minamidaitojima, Japan was investigated. A total of 56 individuals belonging to six species, Heleanna fukugi Nasu (Tortricidae), Opogona sacchari (Bojer)(Tineidae), Erechthias minuscula (Walsingham) (Tineidae), Anatrachyntis sp. (Cosmopterigidae), Ascalenia sp. (Cosmopterigidae), and Simplicia mistacalis (Guenee) (Noctuidae), were identified. One species H. fukugi, and possibly Ascalenia sp., were considered to utilize the nest as a pupation site, and larvae of the other 4 species were inferred to feed on dead plant material of the nests. Emergence from a bird nest is firstly reported in Simplicia mistacalis and Erechthias minuscula, and the latter species is recorded from Japan for the first time. Species composition of emerged moths differed from previously reported ones, which is characterized by a lack of keratinophagous and chitinophagous tineid moths such as Monopis and Niditinea species.
