The nest of the Asian Giant Hornet (Vespa mandarinia), also known as the "murder hornet," is an intricate structure built to house the colony. Here’s a breakdown of its anatomy:<br /><br />1. Location of the Nest<br /><br />Asian Giant Hornets typically build their nests in concealed, low-to-the-ground areas, such as:<br /><br />Underground burrows (e.g., abandoned rodent holes).<br /><br />Hollow tree trunks or stumps.<br /><br />Sometimes in dense vegetation or crevices.<br /><br /><br />2. Structure of the Nest<br /><br />Outer Envelope:<br />A protective layer made from chewed wood fibers and saliva, forming a papery covering. This shields the inner layers from environmental factors like rain or predators.<br /><br />Comb Layers (Brood Chambers):<br />The nest contains multiple tiers of hexagonal combs where eggs are laid and larvae develop. These combs are horizontally stacked and connected by a central support column.<br /><br />Central Support Column:<br />A sturdy structure that holds the comb layers together and ensures stability within the nest.<br /><br /><br />3. Nest Size<br /><br />The nest grows over time as the colony expands. It can reach up to 60 cm (24 inches) in height and 40 cm (16 inches) in diameter at peak population.<br /><br /><br />4. Inhabitants<br /><br />Queen Chamber:<br />A specialized section in the nest for the queen, located near the center for maximum protection.<br /><br />Worker Areas:<br />Workers tend to inhabit the outer and middle layers of the comb to maintain and defend the nest.<br /><br />Larvae Chambers:<br />Larvae are housed in individual hexagonal cells in the combs. Workers regularly feed them a protein-rich diet.<br /><br /><br />5. Air Ventilation<br /><br />The nest’s design includes small openings or porous sections for ventilation, ensuring proper airflow to regulate temperature and humidity.<br /><br />6. Defense Mechanisms<br /><br />Hornets guard the nest entrance and patrol its immediate surroundings.<br /><br />The structure is built in hidden or hard-to-reach locations to minimize discovery by predators or humans.<br /><br /><br /><br />
