Early embryonic development and external features of developing embryos of the caddisfly, Nemotaulius admorsus (trichoptera: Limnephilidae)
Formative processes of the blastoderm, germ disk, embryonic membranes, and germ band in the trichopteran Nemotaulius admorsus are described, chiefly on the basis of SEM data.
Morphology of sternum V glands in three caddisfly species, Stenopsyche marmorata, Eubasilissa regina and Nemotaulius admorsus (Insecta: Trichoptera)
Histological features suggest that the secretory cells of the sternum V gland of Trichoptera belong to the type of class 3 cells in insect epidermal glands.
Embryonic development of the alimentary canal and ectodermal derivatives in the primitive moth, Neomicropteryx nipponensis issiki (Lepidoptera, Micropterygidae)
The formation of the alimentary canal, nervous system, and of other ectodermal derivatives in the embryo of the primitive moth, Neomicropteryx nipponensis Issiki, is described. The stomodaeum is…
The embryonic development of the primitive moth, Neomicropteryx nipponensis Issiki (lepidoptera, micropterygidae): Morphogenesis of the embryo by external observation
The micropterygid moth Neomicropteryx nipponensis belongs to the most primitive suborder Zeugloptera of the Lepidoptera, and its anterior part later develops into the germ band, while its posterior part is the future amnion.

The egg morphology and successive changes in the developing embryos of the carabid ground beetle Carabus insulicola (Carabidae) are described based on light and scanning electron microscopy observations and provide tangible evidence for the subcoxal theory, that is, that thoracic pleura and sterna are derived from sub Coxal regions.
Embryogenesis of the glowworm Rhagophthalmus ohbai Wittmer (Insecta: Coleoptera, Rhagophthalmidae), with emphasis on the germ rudiment formation
The presence of the following embryonic characters in R. ohbai supports the molecular data placing it within the Lampyridae: 1) formation of a spherical germ rudiment near the anterior end of the egg, and 2) the submerged condition of the developing embryo persists until shortly before revolution.

Mesodermal organogenesis in the embryo of the primitive moth, Neomicropteryx nipponensis Issiki (Lepidoptera, Micropterygidae)
The formation of somites, coelomic sacs, splanchnic mesoderm, fat bodies, circular system, gonads, and musculature in the embryo of the primitive moth, Neomicropteryx nipponensis Issiki, is…
Asymmetric larval head and mandibles of Hydrophilus acuminatus (Insecta: Coleoptera, Hydrophilidae): Fine structure and embryonic development.
The developmental process during metamorphosis that results in wing reduction in females of three species of wingless-legged bagworm moths, Taleporia trichopterella, Bacotia sakabei and Proutia sp.…
Observations suggest that female-specific wing degeneration caused by apoptosis occurs in two steps in these bagworm moths, i.e. in the larval and pupal stages.
