When a bee wants to be groomed, what does it touch another bee with?

When a bee desires grooming, it typically touches another bee with its antennae. Antennae play a crucial role in communication among bees, as they are sensitive organs that detect chemical signals and tactile sensations. When a bee initiates grooming behavior, it often uses its antennae to signal to another bee that it is in need of assistance with cleaning. This grooming behavior is essential for maintaining hygiene within the colony, as it helps to remove debris, parasites, and other contaminants from the body of the bee.

The other choices do not serve the same specific communicative purpose in this context. While legs, wings, and body can certainly engage in various interactions among bees, it is the antennae that are specifically adapted for signaling and engaging in grooming behavior.
