Which species navigates with sun position, polarized light, and spatial memory?

• A. Indigo bunting
• B. Sea turtles
• C. Dung beetle
• D. Honeybees

Answer: (D)

Navigating with multiple cues is a hallmark of honeybees. They use the sun as a compass to set direction and can adjust for the sun’s movement across the sky. They also detect polarized light, which provides a reliable directional reference even when the sun isn’t visible. In addition, bees build a mental map of the surroundings—landmarks and distances—that lets them plan efficient routes back to the hive after foraging. Put together, these three navigational tools—the sun’s position, polarized light cues, and spatial memory—are well documented in honeybees, making them the best match for this combination.
