Abstract: A set of trays for incubation includes a cover tray and a screened tray. The cover tray has a closed end surrounded by a peripheral sidewall that defines a cavity. The screened tray includes a screened panel surrounded by a containment flange that surrounds and extends outward from a first face of the screened panel, and a support structure that extends outward from a second face of the screened panel opposite the containment flange. The support structure has apertures that permit airflow through the support structure. The containment flange and support structure are sized to engage overlying and underlying trays in alignment and at an angle.

Abstract: A bee shelter has a base and a collapsible structure. The base has a bottom surface that engages a ground surface and defines a substantially impermeable barrier above the ground surface. The collapsible structure is positioned on the base and has sidewall panels, a roof panel, and living hinges that connect the sidewall panels and the roof panel. The collapsible structure is foldable between a collapsed state and an erected state. In the collapsed state the sidewall panels and the roof panel are in a stack, and in an erected state the sidewall panels and the roof panel define an inner cavity that has an opening defined by the sidewall panels and the roof panel. The inner cavity is sheltered by the roof panel. Each of the base, the side walls, and the roof panel are water impermeable.
