Epidermolysis bullosa or butterfly wing disease is a rare genetic disorder of connective tissue associated with the formation of blisters. The clinical manifestations are very diverse and affect not only the skin cover, but also mucosal surfaces of the gastrointestinal, urogenital and respiratory systems. A large proportion of patients suffer from severe constipation with the development of megacolon. The case report describes intestinal obstruction in a patient with a dystrophic form of epidermolysis bullosa which required surgical treatment.

Butterfly wing eyespots are developmentally determined at the early pupal stage, when prospective eyespot focal cells underneath the pupal cuticle focal spot function as eyespot organizers in the pupal wing tissue. Here, we performed light microscopy and transmission electron microscopy (TEM) to describe cellular structures of pupal wing tissue with an eyespot organizer immediately after pupation using the Blue Pansy butterfly Junonia orithya. The pupal forewing dorsal epidermis was a pseudostratified monolayer of vertically elongated epidermal cells.

Among the insects with wings clad in scales, the butterflies are the best known and those showing greatest variety of scale types. In the Diptera, some families or particular genera of two large groups are known to bear scales on wings, i.e.

Distribution of Phoenicurusia transcaucasicus (Miller, 1923) in Iran and neighbouring territories is clarified based on analysis of DNA barcodes, the male genitalia and wing pattern of adults. Our study revealed the widespread distribution of Ph. transcaucasicus throughout northern, northeastern and central Iran.

In Lepidoptera (butterflies and moths), the genomic region around the gene is a "hotspot" locus, repeatedly implicated in generating intraspecific melanic wing color polymorphisms across 100 million years of evolution. However, the identity of the effector gene regulating melanic wing color within this locus remains unknown. We show that none of the four candidate protein-coding genes within this locus, including , serve as major effectors.
