"Bumblebees' Ingenious Defense: Unraveling the Evolutionary Coincidence with Asian Hornets"

Researchers have discovered that buff-tailed bumblebees have a remarkable defense strategy against invasive Asian hornets. When attacked, the bumblebees drop to the ground, causing the hornets to lose their grip or fall as well. This allows the bumblebees to wrestle with the hornets until they give up and leave. However, despite their successful defense, the presence of Asian hornets still negatively impacts the growth of bumblebee colonies.

"Bumblebees Unleash Top-Tier Combat Skills to Defeat Asian Hornets"

New research from the University of Exeter reveals that bumblebees have top-tier combat skills when targeted by Asian hornets. The study found that buff-tailed bumblebees drop to the ground when attacked by hornets, carrying the pests down with them. Hornets lose their grip during the fall or the bee fights back until the hornet gives up. The researchers witnessed 120 attacks, with the bee successfully defending itself each time. Asian hornets, also known as yellow-legged hornets, are invasive pests that have spread across mainland Europe and parts of Asia, and have recently been spotted in the US. The findings highlight the importance of protecting pollinators like bees from these threats.

Bumblebees' Surprising Defense Tactics Against Invasive Asian Hornets

Researchers from the University of Exeter have discovered that buff-tailed bumblebees have a unique defensive strategy against Asian hornets. When attacked, the bumblebees drop to the ground, effectively repelling the hornets. However, bumblebee colonies in hornet-dense areas still experience reduced growth rates, indicating negative impacts. Asian hornets, which have invaded parts of Europe and Asia and recently appeared in the US, pose a threat to pollinators. The study highlights the importance of understanding the interactions between invasive species and native pollinators for effective conservation efforts.

Bumblebees' Surprising Defense Strategy Against Asian Hornets

Bumble bees have developed a successful defense strategy against Asian hornets by dropping to the ground when attacked, causing the hornets to lose their grip or engage in a struggle. Researchers from the University of Exeter observed over 120 such attacks and found that the bumble bees were able to fend off the hornets every time. However, bumble bee colonies in areas with high Asian hornet densities experienced reduced growth rates, indicating a negative impact. Asian hornets are invasive species that prey on various insects, including honey bees and bumble bees, and their presence poses a threat to pollinators.
