Host plants and position of the eggs and larval leaf-rolls are recorded for three Pamphilius species feeding on Alnus in Nagano Prefecture, central Honshu, based on rearing experiments made in 2004 to 2005. Host records are Alnus hirsuta Turcz. for Pamphilius nakagawai Takeuchi, 1930, P. archiducalis Konow, 1897, and P. flavipectus Shinohara, 2005, and Alnus matsumurae Call, for P. nakagawai and P. flavipectus. Alnus matsumurae is the first host record for P. flavipectus. Oviposition and leaf-rolls of P. nakagawai and P. archiducalis are usually on the under surface of the leaf, whereas those of P. flavipectus are on the upper surface of the leaf. The position of the eggs and leaf-rolls are newly recorded for P. flavipectus. The adults of P. flavipectus emerged one to three weeks later than those of P. nakagawai.
