Cenchrus (insect anatomy)

The cenchrus (plural cenchri) is a specialized anatomical structure in the insect group known as sawflies. The cenchri are small blister-like lobes on the metanotum of these insects, just posterior to the mesothoracic scutellum, shaped and positioned in such a way as to latch onto the base of the front wings when they are folded at rest. [1]There are corresponding small patches on the wings where the membrane is roughened, to increase the friction against the dorsal surface of the cenchri. This is a unique mechanism among the insects.

This article is about the insect anatomical structure. For other uses, see Cenchrus (disambiguation).
