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

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

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,

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.
