The study involved two groups of honeybees:

1. Experienced foragers: These bees (n = 137) had previous exposure to flowers and were collected from outdoor hives.
2. Naïve foragers: These bees (n = 30) were reared in a flower-free greenhouse environment and had no prior exposure to flowers.

Experimental Conditions

Four flower image conditions were tested:

1. Normally configured greyscale flower pictures
2. Scrambled flower configurations
3. High contrast normally configured flowers
4. Asymmetrically scrambled flowers

Key Findings

1. Discrimination Performance: Both experienced and naïve bees showed better learning and discrimination of normally configured flowers compared to scrambled or highly contrasted flowers.

2. Experience and Innate Abilities: While experienced bees performed better overall, indicating the role of experience, naïve bees also demonstrated an inherent ability to process flower shapes, suggesting a combination of innate neural circuitry and learned behavior.

3. Impact of Contrast: Increasing the contrast of flower images did not improve learning performance, indicating that bees may rely more on the spatial configuration of flower features rather than contrast alone.

Implications

The study suggests that bees have an evolved specialization for recognizing flower shapes, influenced by both hard-wired neural mechanisms and experience. This ability allows bees to efficiently forage by rapidly learning and discriminating between different flowers.

Conclusion

Honeybees, whether experienced or naïve, can effectively learn to discriminate normally configured flowers over scrambled or highly contrasted versions. This indicates a specialized neural processing ability for flower recognition, enhanced by experience but present even without it.

 Angiosperms have evolved to attract specific pollinators using various signals such as scent, color, size, pattern, and shape. Over time, bees and angiosperms have co-evolved, making flowers more attractive to bee vision and preferences. This co-evolution helps bees recognize specific flower traits for foraging. This study investigates whether bees are instinctively tuned to process flower shapes by comparing the ability of flower-experienced and flower-naïve honeybee foragers to discriminate between images of normally configured and scrambled flowers. Additionally, the impact of increasing picture contrast on learning performance was assessed.
