Behavior of White Faced Bees
Aggression and Defensive Tactics
White faced bees, also known as Hylaeus anthracinus, are a fascinating species known for their unique and defensive tactics. While some bees are known for their docile nature, white faced bees can exhibit a level of aggression when they feel threatened or their nests are disturbed.
When it comes to aggression, white faced bees are not afraid to defend themselves. They have a distinctive defensive tactic of “buzzing” or buzzing around the perceived threat. This buzzing is accompanied by a loud buzzing sound, which can be intimidating to predators or anyone who comes too close to their nests. This aggressive buzzing is a warning sign to stay away and serves as a means of self-defense.
Another defensive tactic employed by white faced bees is their ability to sting. While their sting is not as potent as that of other bees, it can still cause discomfort and pain. They use their stingers as a last resort when they feel their lives are in immediate danger. It’s important to note that only female white faced bees have stingers, as males lack this defensive mechanism.
Nesting Habits
White faced bees have unique nesting habits that set them apart from other bee species. Unlike honeybees that build elaborate hives, white faced bees are solitary bees that nest individually. They prefer to nest in pre-existing cavities, such as hollow stems, plant crevices, or even abandoned beetle burrows.
These bees are not picky when it comes to nesting locations, as long as it provides protection and meets their needs. The female white faced bees carefully select a suitable nesting site and then proceed to construct their nests. They create individual cells within the nesting site, using a combination of materials such as mud, plant fibers, and other natural resources.
Each cell is carefully provisioned with a mixture of pollen and nectar, which serves as food for the developing larvae. Once the cell is fully provisioned, the female lays a single egg inside and seals it off. The larvae will then hatch, feed on the provisions, and eventually pupate before emerging as adults.
The nesting habits of white faced bees play a vital role in their survival and the continuation of their species. By nesting individually, they are less vulnerable to predation and can ensure the survival of their offspring through careful provisioning and protection.
