New insights into bee movements and life cycles have been uncovered after researchers tracked the insects using tiny QR codes glued onto their backs.

Entomologists are gluing tiny QR codes on honey bees to better track the pollinators’ travel habits and life cycles. In doing so, they hope to gain a more complete and accurate understanding of the environmentally crucial creatures,

Researchers put a sensor at the entrance of beehives to register each time the pollinators entered or exited, and how long they were gone.

Scientists glued teeny tiny QR codes, that are smaller than a pinky nail, to the backs of young bees to figure out how much time the pollinators spend buzzing outside their hives,

At Penn State, a new study using QR codes smaller than a fingernail is being done to learn more about bees. KDKA's Jessica Guay spoke with some of the researchers about their work.
