The third of the four pieces forming the upper part of a thoracic segment of an insect. It follows the scutum, and is followed by the small postscutellum; a scutella. See Thorax.
One of the transverse scales on the tarsi and toes of birds; a scutella.
Posteromedian, usually more or less teardrop or shield-like region of the mesonotum posterior to the transscutal articulation between the axillae. [drawing
a triangular gap at the anterior of the wing covers.
in Heteroptera (true bugs), a more or less triangular sclerite located on the thorax behind the pronotum
a hard, triangular plate on the dorsal surface of true bugs, between the base of the wings.
The middle region of the mesonotum or metanotum, behind the scutum. In apocrita, only the mesoscutellum is evident and is simply called the scutellum, whereas in symphyta both the mesoscutellum and metascutellum are present.
The terminal portion of the thorax, usually hemispherical in shape and set apart by a suture.
The part of the middle segment of the thorax, which you can see from above. In stag beetles it is the triangular bit at the top of the wing cases.
a triangular shaped section on the back of Hemiptera and some Coleoptera. It is often the identifying characteristic of Hemipterans or "true bugs".
In nematodes: An enlarged, shield-like phasmid. (Pl. scutella.) ( 14)
The scutellum is the posterior portion of either the mesonotum or the metanotum of an insect thorax; however, it is used almost exclusively in the former context, as the metanotum is rather reduced in most insect groups. In the Hemiptera, and some Coleoptera, the scutellum is a small triangular plate behind the pronotum and between the forewing bases. In Diptera and Hymenoptera the scutellum is nearly always distinct, but much smaller than (and immediately posterior to) the mesoscutum.
