Asia-born yellow-legged hornets ignite high-stakes battle to defend South Carolina bees

An invasion of Asia-origin yellow-legged hornets in South Carolina’s Lowcountry is decimating honeybee colonies and prompting a Clemson-led response to erase nests, kill queens with 'Georgia juice' bait, and deploy climbers and exterminators. The effort has destroyed hundreds of nests since 2024, but eradication is costly and dangerous, and spread to nearby regions remains a concern as public reports guide the work.

Giant East Asian hornet poses bee threats with credit-card wingspan

Giant East Asian hornet poses bee threats with credit-card wingspan

Scientists in the United States and Canada are monitoring sightings of Vespa mandarinia, the large East Asian hornet nicknamed the “murder hornet,” after nests were found and destroyed in the Pacific Northwest. The wasp can reach about 1.6 inches in length with a wingspan of roughly 2.8 inches (about a credit card’s width) and a 6 mm stinger, and its powerful jaws can slice through honeybees. If established, it could seriously threaten pollinator populations, ecosystems, and crop yields. Officials urge not to disturb nests, to report sightings, and to support pollinator-friendly practices to help protect bees.

Queen Bees: A Colony-Crafted Path to Royalty

Queen Bees: A Colony-Crafted Path to Royalty

New research shows honeybee queens are shaped by a colony’s engineering, not just royal jelly. Young worker bees build specialized, heat-retentive queen chambers from unique wax and, through a dedicated group called queen cell builders, actively nurture future queens. Even with the same diet, larvae raised in queen wax develop better than those in worker wax, underscoring that the environment and social structure are key to queen development and colony reproduction.

Quorum Wisdom: How Scout Bees Steer a Swarm to the Best Nest

Bees decide where to relocate not by a vote but via a quorum-based process: scout bees explore multiple potential cavities, advertise promising sites with waggle dances that encode site quality, and once about 15 scouts cluster at a single site, the swarm mobilizes and leaves for the chosen nest—often the best option, though the process can take two to three days and costs energy for accuracy.

Invasive yellow-legged hornet spotted in Pacific Northwest

Invasive yellow-legged hornet spotted in Pacific Northwest

A live yellow-legged hornet (Vespa velutina) was found April 30 aboard a ship at the Port of Vancouver on the Lower Columbia River and is being monitored after traps were set; experts warn this invasive, more mobile hornet—smaller than the notorious northern giant hornet—could threaten Northwest honeybees and agriculture and might spread coast-to-coast, though no further nests have been found yet.

Royal cradle: bespoke queen-cell wax shapes honeybee destiny

Royal cradle: bespoke queen-cell wax shapes honeybee destiny

A Nature 2026 study shows queen cells are built from specially engineered wax that is chemically and physically distinct from worker wax: richer in unsaturated fatty acids, with lower density and strength but a higher melting temperature. A younger, dedicated crew of bees heats the wax to ~40°C to shape the royal nursery, altering its chemical signature. Grafting queen larvae into standard worker wax caused high mortality (62.5%), suggesting that wax properties, alongside royal jelly, influence queen development and that honeybees use a specialized queen-rearing process. Researchers say the findings may extend to other bee species as well.

Toddler’s question uncovers bees that heat queen cells, revealing a new worker role

A study led by Kai Wang in Beijing, spurred by a toddler’s question, reveals a new worker-bee class—the 'royal engineers'—that heats its thorax to soften wax and sculpt queen cells. Queen-cell wax is structurally distinct (less dense, more pliable, higher melting point) and appears to create a microenvironment crucial for queen development, challenging the idea that royal jelly alone determines queen fate. Queen cells are thus engineered environments, not just passive containers, highlighting the bees’ sophisticated architectural behavior.

Bees with tiny brains master human-face recognition

Researchers trained honeybees (~1 mm brains) to distinguish human faces using photographs and rewards; the bees achieved 80–90% accuracy and remembered the trained face for at least two days, even when faces appeared from different viewpoints. The bees relied on configural processing—the relationships between facial features—similar to humans, challenging the notion that such high-level recognition requires large brains or specialized neural regions. The findings suggest that small neural systems with general learning rules can solve complex visual tasks and may inform AI approaches to recognition with limited resources.

Hybrid California Honeybees Show Natural Edge Against Varroa Mites

Hybrid California Honeybees Show Natural Edge Against Varroa Mites

UC Riverside tracked 236 colonies from 2019–2022 and found locally adapted hybrid California honeybees maintain lower Varroa mite loads—about 68% fewer mites and five times less likelihood of needing chemical treatments—than commercial queens. Lab tests also showed Varroa mites are less attracted to larvae from hybrid bees, especially around seven days old, hinting at a genetic defense formed early in development. The bees aren’t fully resistant, and researchers aim to identify the traits for future breeding to reduce chemical reliance and bolster global pollinator health.

Californian Hybrid Bees Naturally Fight Varroa Mites, Study Finds

Researchers from UC Riverside report that a locally adapted Southern California honeybee population, often feral, shows strong resistance to Varroa destructor mites, with colonies led by Californian hybrid queens exhibiting 68% fewer mites and five times less need for chemical treatments; larval studies indicate mites are less attracted to these bees, suggesting a genetic basis for resistance that could inform breeding programs to improve bee health and crop pollination.
