Examples of forewing in a Sentence
The female also has two spots on the upper forewing.
The name was first used by Linnaeus (1735), who derived it from the half-coriaceous and half-membranous condition of the forewing in many members of the order.
The Anthocoridae are nearly related to the Cimicidae, but the wings are usually well developed and the forewing possesses cuneus and embolium as well as corium and clavus.
The Acridiidae have the feelers and the ovipositor relatively short, and possess only three tarsal segments; their ears are situated on the first abdominal segment and the males stridulate by scraping rows of pegs on the inner aspect of the hind thigh, over the sharp edges of the forewing nervures.
The adult moths have a grayish forewing with an angled darker marking just inside the cleft.
The Locustidae (see Grasshopper, Katydid) have the feelers and often also the ovipositor very elongate; the foot is four-segmented; the ears are placed at the base of the foreshin and the stridulation is due to the friction of a transverse " file " beneath the base of the left forewing over a sharp ridge on the upper aspect of the right.
Many moths have a kidney shaped mark (reniform stigma) roughly two thirds of the way back on the forewing.
