A flower might be yellow or white to our eyes. Photoreceptor activity data showed that honey bees can clearly see objects as small as 1.9 degrees, which is 30 percent better than previous reports. Bees see ultraviolet as a separate color, something we cannot do without sophisticated instruments, and even then, it is only something we can approximate. Adapted from Theobald et al. 2 Bumble bees were unable to see in the dark experimental conditions. Bees can fly in light rain but will avoid it if possible.

Snow blindness is one result of too much UV, as is sunburn. They don't see the colors in plants the way we do. As the season progresses the dark colored honeycomb expands as the amount of brood extends to the new brood frames. To test the bees’ feature detectability threshold, the team recorded deflections in membrane potential induced by dark objects of various sizes drifting through the receptive area of the bees’ visual field. Yes, it depends on the intensity of light available during the night. They see these shiny petals and associate them with sugar. Very few insects can see at night. But those plants have ultraviolet pigments that call out to bees, and guide them to their pollen-bearing parts. Honey bees consume about 8.4 lb (3.8 kg) of honey to secrete 1 lb (454 g) of wax, so it ... Broodcomb becomes dark over time, because of cocoons and shed larval skins embedded in the cells, and the tracking of many feet, called travel stain by beekeepers when seen on frames of comb honey.
