Bumblebees can connect differences in pollen quality before landing: Scientists

Not all flowers are created equal and now, it turns out that bumblebees can tell the difference. Scientists have found that these insects can connect differences in pollen quality with floral features, like petal color, so that they only land on flowers that offer the best rewards. Bees don’t ingest pollen while foraging on flower. That’s why researchers have long wondered how these insects could form associative relationships between what a flower looks like and the quality of its pollen. In order to find out, […]

Bumblebees can fly higher than Mount Everest: Study

Bumblebees may be capable of scaling Earth’s tallest peaks, flying higher than Mount Everest, according to new research. According to the researchers, It’s difficult for most insects and birds to fly at extremely high altitudes where the air is thin and oxygen is scarce. Flapping wings push against the air to generate lift, and the thinner the air, the less force those wings can produce. Yet bumblebees are abundant in high alpine regions.
