Abstract

Analysis of the frequency with which the idiosomal setae occur on the adult females of 1,545 species of Phytoseiidae suggests that there has been discontinuous variation in the suppression of these setae. The process of suppression is more advanced with the setae first expressed in the postlarval stages of ontogeny than with those first expressed in the larval stage. The evolutionary significance of these observations is discussed.
