Prior to forming a cocoon, the larvae of the moth species Oruza yoshinoensis (Wileman), Arasada ornata (Wileman), Autoba tristalis (Leech), O. glaucotorna (Hampson), and O. mira (Butler) build elaborate shelters using dead leaves left on branches. I looked for shelters and larvae at a study site on Mt. Kinka in Gifu City, Japan. Larvae were then raised in plastic containers and allowed to make their shelters. Larvae of O. yoshinoensis, A. ornata and O. glaucotorna made very similar shelters despite differences in genus. There were subtle differences between the shelters that distinguished the three species. The shelter-making behaviors of these moth larvae appear to be as useful as morphological characteristics for species classification.

Morphological characteristics of the butterflies belonging to the Pieris dubernardi-group are examined based on the original descriptions, photographs of the type specimens, and newly obtained butterfly specimens. As a result of the examinations and subsequent discussions, taxonomic statuses of the butterflies are confirmed, and a new subspecies of Pieris dubernardi Oberthür, 1884 from Northern Sichuan is described and illustrated. A distribution map of the group is also given.

The larval morphology of Nemapogon bidentata Xiao & Li, 2010 is described. The chaetotaxy of the larva of this species is similar to that of N. granella (Linnaeus, 1758), but the location of seta A3 on the head capsule of this species differs from that of N. granella.

The young larvae of an endangered (vulnerable) butterfly Panchala ganesa loomisi, were found mainly on the upper surface of new leaves. Larval position changed from the upper surface to the lower surface of leaves as larvae matured, and most final-instar larvae were found on the lower surfaces of leaves.
