What is the unique characteristic of the Caucasian bee?

The Caucasian bee is particularly noted for its excessive use of propolis. This characteristic is significant because propolis plays a vital role in maintaining the health and structure of the hive. It helps seal cracks, enhances the durability of the hive, and acts as an antimicrobial agent, thereby protecting the colony from pathogens. The capacity to gather and utilize propolis effectively allows Caucasian bees to create a stable environment within their hives, contributing to overall colony strength and health.

While the other options suggest traits that are not typically associated with Caucasian bees, such as aggressiveness or defensiveness, they are more common in other bee varieties. Caucasian bees are actually known for their relatively gentle nature, making them suitable for beekeeping, especially in populated areas. Additionally, they are also recognized for good honey production capabilities, contrasting the option of low honey production. Understanding the specific traits of this type of bee aids beekeepers in selecting the right strain for their needs.
