  • Development, seasonal polyphenism and cold hardiness of the blue pansy, Junonia orithya orithya (Lepidoptera, Nymphalidae)

    The blue pansy, Junonia orithya orithya (Lepidoptera, Nymphalidae), was reared under a photoperiod of 12L-12D (short day) at 20 or 25℃ or under 16L-8D (long day) at 20, 25 or 30℃, and larval development, seasonal polyphenism and cold hardiness were examined. The mean duration of larval and pupal stages decreased significantly with increase in temperature. The developmental threshold (t_0) and the thermal constant (K) for the larval and pupal stages were 13.7℃ and 208.3 day-degrees, and 13.4℃ and 99 day-degrees, respectively. Although all the adult females maintained under 16L-8D at 20 and 25℃ produced mature eggs one week after emergence, none of those under 12L-12D at 20℃ had produced mature eggs even 14 days after adult eclosion. Adults exhibited seasonal polyphenism in response to the photoperiod and temperature experienced at the larval and pupal stages. Under long-day photoperiods at high temperatures, eyespots developed on the ventral surface of the hind wing in both sexes, with an orange pattern also appearing on the dorsal surface of the hind wing in females only (long-day form). In contrast, under short day at low temperature, the eye spots were obscure and the dorsal surface of the hind wing was usually blue in females (short-day form). The supercooling points for larvae, pupae and adults were approximately -12, -17 and -20℃, respectively, irrespective of photoperiodic conditions.

  • Butterfly assemblage in a snowy temperate satoyama area in Tokamachi City, Niigata Prefecture

    To understand the characteristics of the butterfly assemblage in a snowy temperate satoyama area, transect surveys were conducted nine times from spring to autumn in Tokamachi City, where average annual maximum snow depth is about 3m. A transect route (2.1km) was established, and divided into 14 sections with four vegetation types (four grassland, two protected slope, four forest/wetland edge, and four forest interior sections). In total, 177 individuals from 27 species were observed. This species richness was rather lower than those in other satoyama areas. The numbers of species of oak, bamboo, citrus, and hackberry feeders were especially lower, probably because of scarcity of host plants, but those of viola feeders were equal or higher, probably because of maintenance of grasslands around terraced paddy fields. Grassland and edge sections had higher species richness than protected slope and forest interior sections. Of the two declining species observed in this study (Luehdorfia japonica and Fabriciana adippe), the former used the interior and edges of the forests, whereas the latter used grasslands. Maintenance of grasslands, oak forest patches, and beech forests with the host plants of L. japonica would be essential for conserving the butterfly fauna in this area.

  • A new willow leaf blotch miner of the genus Phyllocnistis (Lepidoptera: Gracillariidae: Phyllocnistinae) from Japan, with pupal morphology and genetic comparison of Salicaceae mining species using DNA barcodes

    A new willow leaf blotch miner, Phyllocnistis gracilistylella sp. nov. (host plants: Salix gracilistyla, S. serissaefolia, S. integra, and S. gilgiana) is described and compared with P. unipunctella (Stephens, 1834) and P. saligna (Zeller, 1839). Phyllocnistis unipunctella is newly recorded from the mainland Japan. Adult morphologies and life histories of the three Salicaceae mining species are described with photographs and illustrations. The pupal morphologies of the new species and P. saligna are described with the use of a scanning electron microscope. The new species and P. saligna occurred together, but differed in the position of the mines; the former utilized only the leaf, mostly the lower surface, while the latter utilized the stem and upper surface of the leaf and partly the leaf edge at the cocoon stage. The new species was clearly divided from P. saligna not only by adult and pupal morphologies but also by DNA barcodes. Molecular analysis using reference DNA barcods also indicated that Japanese representatives of P. saligna are more closely related to P. ramulicola than to European P. saligna.

  • Additional notes on the biology of Apochima excavata (Dyar)

    Larvae of Apochima excavata (Dyar) were observed in the field using the same methods as Funakoshi and Miyano (2010) and were reared in the laboratory in 2010. Additional notes on the ecology, in particular the behavior of the imagines, place of pupation, sex ratio, number of eggs laid and ovipositing position, were investigated to examine the unique adaptation to the habitat and host plant of the species.

  • Pupae of Japanese Callidulidae (Lepidoptera)

    The pupae of two callidulid genera, Callidula Hubner and Pterodecta Butler present in Japan are described. From the pupal characteristics, the Callidulidae as designated by Minet (1989) contains two (or more) conspicuously different families, one (including at least the Pterothysaninae) belongs to the Macrolepidoptera and is related to the Bombycoidea, the other (the Callidulinae) is a sister group of the Hyblaeidae in the Microlepidoptera. True Callidulidae should be restricted to Minet's Callidulinae.
