urite การใช้

The ovipositor is clearly visible, partly invaginated in the seventh urite, which is always black.
Typically there is atrophying of the first urite and the merging of 2 ?and 3 ?urotergites.
In Anthracinae and Bombyliinae, a diverticulum is present in the eighth urite, in which the eggs are mixed with sand before being deposited.
This morphological adaptation is often accompanied by sclerotisation of the terminal eighth urite, so that the ovipositor is able to penetrate through the tissues of the organism which will accommodate the eggs and larvae.
In general, the 10 urites ( one of the segments of the abdomen or post-abdomen ) are reduced to a lower number of urites because of structural modifications of the first urite and the last.
