Why is a drone fly brightly coloured even though they cannot sting?

Bright colors in drones, which are male bees, serve as a form of sexual dimorphism to attract females. These vivid hues can signal fitness and health, making them more appealing during mating. Additionally, their bright coloration may serve as a warning to potential predators, indicating that they are harmless and cannot sting. This strategy helps enhance their reproductive success while ensuring their survival.
