Abstract
A continuous sieving apparatus is described. The continuous sieving apparatus includes a sieve surface attached to a wall. A set of openings is formed in the sieve surface so as to define a set of pathways extending through the sieve surface. The set of opening are defined by a length dimension that is greater than a width dimension. An action system is configured to move the sieve surface in one or more directions (e.g., horizontally and vertically). Such movement causes a first pupa having a first cephalothorax width that is less than the width dimension to move through any one of the set of openings, and a second pupa having a second cephalothorax width that is greater than the width dimension to be prevented from moving through the set of openings.
