Light irradiation stimulates blue coloration in the band region of the adult wing of a butterfly, Graphium sarpedon whereas the region remains yellow in darkness. This blue color is due to the presence of a blue bilin pigment (sarpedobilin). In the present study, we show that the amount of blue bilin in the wing band region increases with increasing intensity or duration of light exposure. Further, blue bilin accumulation occurs when local irradiation of light falls on the wing, but not on the adult body. This remained true even when only the wing separated from an adult body or only the limited region of the wing band pattern was exposed to light. Blue light is more effective than green or red light. Microscopic observations show that the blue coloration is derived from part of the wing membrane, but not from wing scales. These results strongly suggest that light acts directly on the wing tissue without the intervention of a neuroendocrine system, and increases the amount of blue bilin in the wing membrane.

In the Bol'shoy Kavkaz Mountains and their adjacent northern low mountain areas there occur two taxa of the genus Pieris (Pieridae), caucasica Lorcovic and suffusa Sheljuzhko. Based on morphological and ecological characteristics, they are here recognized as two good species with the scientific names of P. bryoniae caucasica and P. pseudorapae suffusa, respectively.

A new micropterigid, Vietomartyria gladiator Hirowatari & Huang sp. nov., is described from Nankunshan, Guangdong, China. Two species, Paramartyira jinggangana Yang, 1980 and P. baishanzuna Yang, 1995 are newly transferred to the genus Vietomartyria Hashimoto & Mey, 2000, with the result that the genus now comprises six species. We consider that Vietomartyria gladiator represents the presently known sister-group of a Glade consisting of the other five species. A check list of Vietomartyria is provided.

This short note demonstrates the morphological evidence of male-specific size reduction of head capsule width during the last larval instar of the bagworm moth Eumeta variegata (Snellen, 1879). In this species, sexual dimorphism appears in the last larval stage, with the male larvae being smaller than female larvae. Head capsule width in the female increases after the last larval molt, while in the male head capsule width is reduced in the last larval instar. These results show that the reduction of the epicranial plate causes the size reduction of head capsules during the last larval instar in males. This is the first description of the process of the male-specific size reduction of head capsule width in lepidopteran insects during the last larval molt.

We describe a new subspecies of Erebia fletcheri Elwes, 1899 (Nymphalidae, Satyrinae) from the upper reaches of the Khurmuli River, Myaochan Mountains, Khabarovskyi kraj, Far-Eastern Russia. The characteristics of the new subspecies are its larger wing size, the shape of the reddish-brown forewing band and the developed eye spots with reddish-brown rings on the hindwing.

Actias selene Hubner, an indigenous vanya silk moth is trivoltine in nature and undergoes 97.6±4.37 days winter pupal hibernation in the climatic conditions of Nagaland, India. The worm is polyphagous in nature and feeds on six host plants, among which rearing was conducted on two host plants, namely, Alnus nepalensis (Alder) and Rhus javanica (Tangmo) in three rearing seasons (March-May, July-August and October-December) for two consecutive years. Each larval instar of A. selene worms has a distinct body colour and tubercular arrangement. On the basis of host plant preference they also exhibit seasonal variation in production parameters (Fecundity, Hatching percentage, ERR percentage and Cocoon/Dfls ratio), life cycle parameters (Duration) and cocoon parameters (Length, Breadth, Weight, Shell weight and Shell ratio). The cocoon has, apparently, no sericultural value, but reelable cocoons with a filament length (mts), filament denier (d) and raw silk recovery (%) of 78.1±4.41-198.82±, 5.09-11.57 and 41.57-58.86% and 86.84±5.40-163.22±8.56, 6.67-8.85 and 35.63-43.32% on Rhus javanica and Alnus nepalensis, respectively, in different rearing seasons are described for the first time.
