In what arrangement are the ocelli located on a bee's head?

The ocelli are simple eyes located on the top of a bee's head, which are arranged in a triangular formation. This triangular arrangement consists of three ocelli: one located at the center and two positioned slightly forward and to the sides. This configuration enhances the bee's ability to sense light intensity and horizon position, which is crucial for navigation and spatial awareness during flight.

The triangular setup allows for effective visual input that helps bees make critical decisions while flying, especially in complex environments. This anatomical structure is specifically adapted to support their lifestyle and activities as pollinators.
