A high-tech approach to monitoring bee activity inside the nest reveals how the neonicotinoid imidacloprid impairs colony growth.

The insects fell silent as the moon cast a shadow over parts of North America last summer, researchers report.

Sulfoxaflor, an alternative insect-killer to older chemicals that decimate pollinators, turns out to kneecap colonies.

Urban colonies had more offspring, survived longer, and hosted fewer parasites.

The first global evaluation of populations demonstrates that certain species are diminishing considerably.

Bumblebees (Bombus impatiens) can amass pollen by “buzzing”—or oscillating—against a flower, creating a gentle flurry of grains.

Two large studies find that, in real-world conditions, the insecticides are detrimental to honey bees and bumblebees.

Scientists report that thiamethoxam exposure impairs bumblebees’ reproduction and honey bees’ ability to fly.

Worker bumblebees vary in how efficiently they bring pollen and nectar back to the hive—the most active foragers can make up to 40 times more trips than the least active ones.
