What distinguishes bees from wasps in terms of their body characteristics?

Bees are distinguished from wasps by their body characteristics in that they are typically covered in hair. This hair is crucial for their role in pollination, as it helps them collect and transport pollen from flower to flower, which is essential for the reproduction of many plants. The presence of hair on bees' bodies allows them to effectively gather pollen grains, enhancing their efficiency as pollinators.

In contrast, wasps generally have smoother bodies, which are less hairy and streamlined for hunting or scavenging rather than for pollen collection. Additionally, while bees can sting, their more robust and hairy bodies are often designed for different survival tactics, such as foregone aggression in favor of protection through pollination roles. The difference in body shape also means that wasps usually have more elongated bodies, which is less common in bees. Therefore, the presence of hair on bees is a key distinguishing factor that supports their lifestyle and ecological role.
