Evolution and phylogeny of basal winged insects with emphasis on mayflies (Ephemeroptera)
… a monophyletic group of semi-aquatic pterygote insects, comprising 3083 species, 376 genera, and 37 described families and are present on all continents, excluding Antarctica, being associated with freshwater and brackish water habitats. The order is unique among pterygote insects in possessing …

How does a butterfly embryo cope with environmental stress?
… both survival and development. The majority of winged insects, including butterflies, develop a protective sheet of cells surrounding the embryo during early embryogenesis. This sheet of epithelial cells is called the serosa and appears to protect the embryo against toxins, desiccation and …

Micromechanical actuators for insect flight mechanics
… a similar role to that of the hind wings of two-winged insects, detecting Coriolis forces and thereby mediating flight stability during maneuvers. Early evidence suggests that mechanical stimulus of the antennae may enable flight control. In addition, the crepuscular hawk moth Manduca Sexta has a …
