1. A separation apparatus for separation of non-adult insects, comprising:
a support base;
an inclinable tub pivotably coupled to the support base about a pivot axis, the inclinable tub comprising:
a rear portion defining a rear flow space;
a front portion defining a front outflow space;
two tub sidewalls extending between the rear portion and the front portion;
a tub floor defining a flow surface;
a plurality of height-adjustable bars, each extending between the tub sidewalls and defining a gap having a gap height between a lower edge of the corresponding height-adjustable bar and the flow surface in a direction perpendicular to the flow surface;
a plurality of bar positioning assemblies, each configured to increase or decrease the gap height of a corresponding one of the plurality of height-adjustable bars by independently adjusting the position of the corresponding height-adjustable bar relative to the flow surface, without affecting the gap height of any other one of the plurality of height-adjustable bars;
at least one extensible member comprising a member upper end coupled to the inclinable tub, and a member lower end coupled to the support base;
wherein the at least one extensible member is configured to transition the inclinable tub between a front-downward inclination of the flow surface, defining a positive inclination angle α between a horizontal plane and the flow surface, and a front-upward inclination of the flow surface, defining a negative inclination angle β between a horizontal plane and the flow surface.
