In turn, the notum of the prothorax is called the pronotum, the notum for the mesothorax is called the mesonotum and the notum for the metathorax is called the metanotum. Continuing with this logic, there are also the mesopleura and metapleura, as well as the mesosternum and metasternum. [8]
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum ( dorsal ), the prosternum ( ventral ), and the propleuron ( lateral ) on each side.
The metathorax is the posterior of the three segments in the thorax of an insect, and bears the third pair of legs.Its principal sclerites (exoskeletal plates) are the metanotum (), the metasternum (), and the metapleuron on each side.
prothorax The first segment on the thorax anterior to the mesothorax. pterostigma (plural pterostigmata) The prominent cell, usually opaque and coloured, near the tip of each wing of the Odonata, on the anterior margin; also, more loosely, called stigma. pterothorax The meso- and metathorax of winged insects, that carries the two pairs of wings.
The notum (plural nota) is the dorsal portion of an insect's thoracic segment, or the dorsal surface of the body of nudibranch gastropods. The word "notum" is always applied to dorsal structures; in other words structures that are part of the back of an animal, as opposed to being part of the animal's ventral surface, or underside.
The race for female actor in a comedy series pitted host Kristen Bell vs. presenter Quinta Brunson vs. almost-host Jean Smart vs. two co-workers (Liza Colón-Zayas and Ayo Edebiri) from The Bear.
Thorax: The prothorax is usually reduced. Wings: Two pairs of wings are present in almost all taxa. The wings have very few cross veins. Abdomen: The posterior abdominal segments are extensively modified for reproduction. Cerci are absent. Larva: Lepidoptera larvae are known as caterpillars, and have a well-developed head and mandibles.
