What is a characteristic feature of bumblebees?

A characteristic feature of bumblebees is their fuzzy appearance combined with distinct black and yellow markings. This distinctive coloration serves multiple functions, such as attracting mates and providing warning coloration to potential predators, indicating that they might be capable of stinging. The fuzzy texture of their bodies also helps in the process of pollination by allowing them to carry more pollen as they move from flower to flower. Bumblebees are social insects, typically living in small colonies, which contrasts with solitary behavior and nesting habits mentioned in some of the other options.

Their ability to sting is also a significant aspect of their behavior, countering the idea presented in one of the choices that they do not sting at all. Understanding these features highlights the importance of bumblebees in ecosystems, especially in pollination, and illustrates their unique role compared to other types of bees.
