The mouthparts are on the underside of the head and include simple chewing mandibles. [1] Exoskeleton of head, thorax, and first two abdominal segments: [3] A. Austrophlebia costalis (dragonfly), female; dorsal view. B. The same, ventral view. C. The same, lateral view. D. Head of the same, front view. E. Head of Lestes (damselfly
Hair-plates are proprioceptors [1] and provide information to the nervous system about the positional and movement state of the body and legs. Hair plate neurons come in two flavors, one that responds phasically (rapidly adapting) and another that responds tonically (slowly adapting) to transient or maintained deflections of the hairs.
A tergum (Latin for "the back"; pl.: terga, associated adjective tergal) is the dorsal ('upper') portion of an arthropod segment other than the head. The anterior edge is called the 'base' and posterior edge is called the 'apex' or 'margin'.
The cockroach is flattened dorsolaterally and is roughly oval with a shield-like plate, the pronotum, covering its thorax and posterior region of the head. The antennae are many-segmented, long and slender, and the mouthparts are adapted for chewing. The forewings are normally leathery and the hind wings membranous.
The head capsule bears most of the sensory organs, including the antennae, ocelli, and compound eyes, along with the mouthparts. In the adult insect, the head capsule appears unsegmented, though embryological studies show it to consist of six segments that bear the paired head appendages, including the mouthparts, each pair on a specific ...
Dorsal ocelli are light-sensitive organs found on the dorsal surface or frontal surface of the head of many insects, including Hymenoptera (bees, ants, wasps, sawflies), Diptera (flies), Odonata (dragonflies, damselflies), Orthoptera (grasshoppers, locusts) and Mantodea (mantises). These ocelli coexist with compound eyes; thus, most insects ...
The desert cockroach can gain weight by absorption of water vapor from unsaturated atmospheres above 82.5% relative humidity.Blocking the anus or the dorsal surface with wax does not prevent water vapor uptake, but interference with movements of the mouthparts or blocking the mouth with wax prevents such uptake.
A chewing insect has a pair of mandibles, one on each side of the head. The mandibles are caudal to the labrum and anterior to the maxillae . Typically the mandibles are the largest and most robust mouthparts of a chewing insect, and it uses them to masticate (cut, tear, crush, chew) food items.
