An inner cover for a beehive and methods of making the inner cover in accordance with the present disclosure are primarily characterized by a substantially rigid base and a substantially rigid banding defining a volume within the inner cover. The base includes one or more ventilation openings which may optionally be covered by a screening material. The screening material, or the ventilation openings themselves, may be selectively blockable and unblockable by bees through the use of available materials such as propolis or beeswax. Self-variation by the bees of ventilation within the inner cover controls air circulation and temperature regulation, improving the survivability of the bees within a beehive as outside temperatures vary and allowing for year-round use. Food may be placed upon the ventilation openings, screening material, or surrounding structure, allowing bees to feed and regulate their environment without the risks of breaking cluster.
