title: Ultrastructural studies of development and light-dark adaptation of the eye of Coccinella septempunctata L., with particular reference to ciliary structures.
abstract: On dark-adaptation of the 11-day adult eye, the rhabdomers move towards the cuticle. Each c-c-r array (of tandem centrioles and ciliary root) maintains its position relative to the rhabdomere, and the length of the root is apparently unchanged. The close association of the array with the rhabdomere is not established until after the first day of adult life. The array is already present at the time of pupation. The distal centriole subsequently becomes the basal body of a transitory ciliary bud, whole formation apparently precedes the onset of rhabdomere differentiation.
