Bees have a layer of fine, water-repellent hairs on their bodies that trap air and make them more buoyant. This allows them to float on the surface of the water even when they are fully submerged.
When a bee drowns, its body starts to decompose and release gases, which form bubbles on the surface of the water. These bubbles are a result of the decomposition process, and not a sign of the bee being alive.
No, not all insects have the same water-repellent hairs on their bodies as bees do. Some insects, like mosquitoes, do not have these hairs and will sink when they drown.
The length of time a drowned bee can float depends on various factors such as water temperature, size of the bee, and how much water it absorbs. Generally, a bee can stay afloat for a few hours to a few days before it sinks to the bottom.
No, the bee is not alive when it is floating and producing bubbles. The buzzing sound that is sometimes heard from a drowned bee is caused by the bubbles popping as they reach the surface of the water, and not from the bee being alive.
