Daily activity patterns of Idea leuconoe (Erichson) were investigated in the butterfly house. Flower visiting activities of butterflies tended to be concentrated from 10:00 to 15:00. The pattern of chasing activities and flying activities showed a single peak from 11:00 to 12:00. Oviposition activities tended to be concentrated in the afternoon. The peak of oviposition activities was later than that of chasing and flying activities.

We report here on lepidopteran larvae associated with two different types of leaf galls. 1) We examined the relationship between the structural features of one type of leaf gall and the feeding preference of two polyphagous caterpillars. On a Distylium racemosum (Hamamelidaceae) tree bearing leaf pouch galls formed by the aphid Neothoracaphis yanonis (Matsumura) (Homoptera, Aphididae) during the spring in an urban park, caterpillars belonging to the species Lymantria dispar (Linnaeus) and L. mathura Moore (Lymantridae) rested on its leaves. The galls were dehiscent, and most alates of the aphids had already escaped the galls. The galls showed no signs of having been attacked by lepidopteran larvae. We brought the larvae back to our laboratory, enclosed them in plastic cups containing D. racemosum galled shoots, and inspected the plant parts on which the larvae had fed. L. dispar and L. mathura larvae fed on normal leaf tissue and dehiscent openings on the underside of the galls but avoided feeding on their round upper surfaces. Since damage by caterpillars feeding on the galls was rare and occurred after alate emergence if at all, the caterpillars posed no negative effects for the aphids. 2) Leaf-roll galls of Phyllocolpa sp. (Hymenoptera, Tenthredinidae) on a Salix eriocarpa (Salicaceae) tree on a riverbank were sampled during the spring. Among them, 1.5% (N=206) had been attacked by the larvae of Clostera anachoreta ([Denis & Schiffermuller]) (Notodontidae), Orthosia angustipennis (Matsumura) (Noctuidae) and L. dispar, which are facultative cecidophages (gall-feeders). C. anachoreta and O. angustipennis had invaded and fed on the galls, while L. dispar had grazed on them from the outside. The impact as a result of moth larvae feeding on the survival and development of sawfly larvae was small, since the attack rate was only 1.5% and there was no gall in which sawfly larva died due to cecidophage feeding activity. The two gall formers in this study exhibited a low mortality attributable to the feeding activity of cecidophagous Lepidoptera. This might be as a result of the roundness and hardness characteristic of pouch galls produced by aphids, which deterred assault by the cecidophages, and because the relatively short developmental period of the sawfly larva reduced the chance of cecidophage attack.

Fifteen Japanese species of the family Incurvariidae (Lepidoptera) are dealt with. Three species, Phylloporia bistrigella (Haworth, 1828), Excurvaria praelatella ([Denis & Schiffermuller], 1775) and Incurvaria vetulella (Zetterstedt, 1839) are newly recorded from Japan. The females of Paraclemensia oligospina Nielsen, 1982 and P. monospina Nielsen, 1982 are reported for the first time and the genitalia are described. The male and female genitalia of Incurvaria alniella (Issiki, 1957) and I. takeuchii Issiki, 1957 are described. Photographs of the adults of all the 15 species and the larvae of 5 species with the host plants, illustrations of the adult heads, wing venations, female 7th abdominal sternum and tergum and the male and female genitalia are provided. The host plants of Procacitas orientella (Kozlov, 1987), Alloclemensia maculata Nielsen, 1982 and I. takeuchii Issiki were found to be Pyrola incarnata Fischer (Pyrolaceae), Viburnum furcatum Blume ex Maxim (Caprifoliaceae) and Clethra barbinervis Siebold & Zucc. (Clethraceae), respectively.

Morphology of immature stages of a Japanese lyonetiid moth, Lyonetia euryella Kuroko is described. By comparing with L. prunifoliella (Hubner), and L. anthemopa Meyrick, it is suggested that larval chaetotaxy, pupal frontal horn and its superficial structure, and projected tracheae and spines of 10th abdominal segment are useful for the taxonomy.

A species of the Apatulinae, Hestina nicevillei (Moore, 1896) was recently found in Ha-Giang, Northern Vietnam, and we here describe it as a new subspecies: Hestina nicevillei magna. It is also the first record of sympatry of the species with the allied species H. assimilis (Linnaeus, 1758). This subspecies is clearly distinguishable from other subspecies by its large size and much reduced black markings on the upperside of both wings, as well as a tiny, faint red submarginal spot on the hindwing reminiscent of the characteristic red markings of H. assimilis. It is known that H. nicevillei represents a classic case of Batesian mimicry, since the color pattern in all the subspecies hitherto known is remarkably similar to the local forms of Aporia agathon (Gray, 1831), which is considered to be offensive for birds. It is puzzling, however, that this model pierid species has thus far not been found in the area around Ha-Giang, although a large number of butterflies have been collected. On the other hand, Aporia giganthea Koiwaya, 1993, which is common there in spring, looks somewhat similar to ssp. magna in size and coloration. Furthermore, the white seasonal form of Hestina assimilis is also common, which at the first glance is almost indistinguishable from ssp. magna both in size and color pattern. Some possibilities regarding the origins of the unique features of H. nicevillei magna are discussed with special reference to the phenomena of mimicry and convergence.

Blastodacna ochrella sp. nov. is described on the basis of specimens collected in the eastern part of Hokkaido and in the central part of Honsyu, Japan. The anellus lobes of the male genitalia are parallel-sided on the basal half and abruptly tapering on the distal half. This character indicates that the species is much closer to B. lvovskyi Sinev, 1986 and B. mironovi Sinev, 1989 distributed in Central Asia, than to any of the congeneric species previously recorded in the Far East. Investigations into the vegetation at Miwa, Kosimizu-tyo, Hokkaido, where adult moths of the new species were very frequently collected, imply that the species is associated with Prunus sargentii or Sorbus alnifolia.
