What are ocelli in honeybees?

• A. Complex eyes for color detection
• B. Simple eyes that detect light and darkness
• C. Organs for producing honey
• D. Glands for pheromone production

Answer: (B)

Ocelli are simple eyes found on the top of a honeybee's head, and they play a crucial role in light detection. Unlike the compound eyes that honeybees use for seeing detailed images and detecting colors, ocelli are primarily responsible for sensing changes in light intensity. They help bees with orientation and navigation, especially during foraging flights and in low-light conditions. These simple eyes can detect light and darkness, contributing to the bee's overall sensory perception and aiding in their ability to return to the hive. The other options present functions that do not align with the role of ocelli. Complex eyes do involve color detection but are associated with the compound eyes, which are distinctly different from ocelli. Honey production is a function of specialized glands in worker bees, and pheromone production is likewise linked to specific glands, neither of which relates to the ocular function of ocelli.
