In 2003, we marked 44 individuals of Luehdorfia japonica at the five peaks (Peaks A-Peak E) of Mt Egesan, and tried to recapture them at the peaks. We detected 25 occurrences of peak-to-peak translocations by 13 individuals, and 15 translocations among the 25 were manifested on the same day. Direct peak-to-peak distances were, Peak A-Peak E, 460 m; Peak D-Peak E, 420 m; Peak A-Peak D, 340 m; and Peak A-Peak B, 125 m. In 2004, we marked 27 individuals, and eleven translocations on 5 individuals were detected. Eight translocations among the eleven occurrences were detected on the same day. In 2005, we marked 52 individuals, and 17 translocations on nine individuals were detected. Five translocations among the 17 occurrences were detected on the same day. As is also explained in another manuscript (Watanabe and Hirano, 2006), the male flight behaviors of Luehdorfia japonica at the summit area are categorized into at least three types; round-patrolling with rests at specific points, perching occupation with repeated circular flights, and peak-to-peak translocation. Implications of the flight behaviors are discussed in regards to the mating activities of males coupled with the avoidance of population divergence.

Parnassius citrinarius tears the cocoon with a hook organ located at the base of the forewing upperside. There are two hooked processes on each wing. One is rose-thorn shaped, about 0.1 mm in height, 0.1 mm in diameter in base; another, also on the wing, is about 0.4 mm in length, 0.2 mm in diameter. Only the rose-thorn shaped hooks were used for emergence from the cocoon.

The adult female of the tussock moth, Orgyia recens, has vestigial wings. However, there was no difference in wing development between sexes until pupation. Even in the beginning of the pupal stage, females retained well-developed wing discs as large as those of males. Then the histological change of female pupal wing epithelia of this species was observed using light microscopy. As a result, wing degeneration was observed in the female wing epithelium just after the adult differentiation began. Phagocytosis was also observed during the wing degeneration in the central large area of pupal wing epithelia. These results strongly suggest that the wing degeneration of O. recens was caused by programmed cell death.

We found that in Ishigakijima Island, there are two populations of the pierid butterfly Eurema hecabe (L.) differing in adult size. Field observations and rearing experiments showed that large adults occur when larvae developed on Ormocarpum cochinchinense while small adults occur when they developed on Medicago polymorpha, suggesting that the difference in adult size depends on the food plant species used, rather than a genetic factor.

Host plants of Celastrina sugitanii Matsumura were surveyed in the southern part of Kanagawa Pref. (Tsukui-town, Sagamiko-town and Hakone-town), where a well-known host plant, Aesculus turbinata, is not distributed. Cornus controversa, Phellondendron amurense, Wisteria barachybotrys and Robinia pseudo-acacia were confirmed as its host plants in this area, and the last two were newly added to the host range of C. sugitanii.

Usage patterns of nectar resource plants by butterfly communities were studied from April to November 2004 in the Arakawa river basin, Adachi-ku, Tokyo. 12 varieties of nectar resource plants were recorded in this study. These were conspicuous herbaceous and perennial plants commonly seen in grassland in the Arakawa river basin. Resource breadth of butterflies was variable among butterfly species. It was positively correlated with both number of nectar resource varieties utilized by butterflies and numbers of butterflies observed to use the resource plant.

Experimental treatment of pupae with cold shock or tungstate, a protein-tyrosine phosphatase inhibitor, produces a series of unique wing color-pattern modifications in adult butterflies. Being similar to the tungstate-induced modifications, several Vanessa species can be arranged in a series of the systematic color-pattern differences largely based on the relative area of orange (RAO) on the forewings. The hypothetical molecular pathway that is sensitive to cold shock or tungstate has been proposed to be involved in speciation of these butterflies. Here we investigated phylogeny of Vanessa and its related butterflies in reference to DNA sequences of the mitochondrial NADH dehydrogenase subunit 5 gene and cytochrome oxidase subunit I gene. Seven species that belong to the conventional Vanessa genus were separated into two groups: Five species, V. indica, V. samani, V. dejeanii, V. dilecta, and V. buana, formed an independent cluster with strong bootstrap support ("the indica group"), excluding V. atalanta and V. tameamea as a separate clade ("the atalanta group"). Thus, the indica group contains five species with various RAO values including V. samani (which has large RAO value) and V. dejeanii (which has small RAO value). Similarly, the atalanta group consists of two species, V. atalanta and V. tameamea, whose RAO values are quite different from each other. Our data argue for the evolutionary model in which the conventional Vanessa genus, but not its related genera, has a unique tendency to evolve "bi-directionally" to species with large or small orange area on the forewings beyond phylogenetic constraint from either the indica or atalanta groups within the genus.
