According to the study, bees were offered “artificial nectar that containted various natural sugar levels and various levels of caffeine and nicotine, alongside clean nectar that comprised sugar alone.” The bees indicated their preference for the nicotine version of nectar.
Talking of bees, they are also known to have what are called “compound eyes” – which consist of thousands of individual photo receptors. From Wikipedia: “The image perceived is a combination of inputs from the numerous ommatidia (individual “eye units”), which are located on a convex surface, thus pointing in slightly different directions. Compared with simple eyes, compound eyes possess a very large view angle, and can detect fast movement and, in some cases, the polarization of light.”
