Female Bumble Bees and Stinging
Bumble bees possess stingers, an anatomical feature they use for defense. Understanding their stinging behavior can help clarify common misconceptions about these important pollinators.
Only female bumble bees, including both queens and worker bees, have stingers. Male bumble bees, known as drones, lack this defensive mechanism entirely. The stinger is a modified ovipositor, which in other insects is used for laying eggs, but in female bees, it serves solely for defense.
Bumble bees primarily use their stingers to protect themselves or their nest. They are not inherently aggressive and typically sting only when provoked. Actions like swatting at a bee, disturbing their nest, or accidentally stepping on one can trigger a defensive sting.
A foraging bumble bee is unlikely to sting, as they are usually focused on their task and will only resort to stinging if directly threatened. Remaining calm and moving slowly away from a bumble bee can help prevent a sting.
The Nature of a Bumble Bee Sting
A bumble bee’s stinger is smooth, lacking the barbs found on the stingers of some other bee species. This smooth design allows the bumble bee to retract its stinger after an attack. Consequently, a bumble bee can sting multiple times without harming itself.
When a bumble bee stings, it injects venom into the skin, which typically causes immediate, localized pain. This pain is often followed by symptoms such as redness, swelling, and itching around the sting site. These reactions are usually mild and subside within a few hours to a few days.
While most reactions are localized and non-allergic, severe allergic reactions, though rare, can occur in sensitive individuals. Approximately 1% of people may experience an allergic response to bumble bee venom. Such reactions might include symptoms beyond the sting site and require medical attention.
Bumble Bees vs. Other Stinging Insects
Bumble bees differ significantly from other stinging insects like honey bees and wasps in their stinging behavior and stinger characteristics. Honey bees, for example, possess barbed stingers, which typically remain embedded in the skin after a sting. This results in the honey bee dying shortly after stinging, as its internal organs are torn away.
In contrast, a bumble bee’s smooth stinger allows it to sting repeatedly without dying. While some wasps can also sting multiple times, bumble bees are generally less aggressive than many wasp species.
Wasps may exhibit more persistent or proactive defensive behaviors, especially around food sources or their nests. Bumble bees primarily sting as a defensive measure for themselves or their colony, unlike some wasps that might sting more readily in perceived territorial disputes.
