Explanation
Foraging and pollination: what we know about bees
Food serves different functions for bees: nectar provides energy, while pollen provides protein and other nutrients. As bees transfer pollen between plants, they also contribute to pollination. The available evidence helps explain this connection, but does not allow us to reconstruct detailed foraging routines or extend them to all pollinating insects.
A broad topic, limited evidence
“Pollinating insects” encompasses many groups, but the specific informational source in the nutrition package concerns bees. This article therefore focuses on bees and on the relationship between two resources—nectar and pollen—and the transfer of pollen between plants; it does not describe a universal foraging pattern for all insects. [1479]
Two resources, different functions
The supported explanation distinguishes the role of each resource: nectar provides energy, while pollen provides protein and other nutrients. The source also states that most pollen is used as food for larvae. This helps explain why collecting both resources can be part of bees’ nutrition, without attributing to them a foraging sequence or technique that the material does not document. [1479]
When feeding connects plants
The same source states that, while collecting food, bees also transfer pollen from one plant to another, and that this transfer provides pollination services. The connection described is specific: an activity related to obtaining resources can move pollen between plants. The package does not specify how this transfer varies by bee species, flower, or environmental conditions. [1479]
What is established and what cannot be concluded
The supported facts include the functions attributed to nectar and pollen, the use of most pollen as larval food, and the transfer of pollen between plants. The explanation connecting them is that bees’ feeding can be accompanied by pollination. The material provides no evidence for hypotheses about routes, preferences, learning, or decisions during foraging: here, these are unanswered questions, not findings. [1479]
The limits of comparison
The package mentions that interactions between orchids and their pollinators are complex, but this general description provides no specific examples of foraging behavior that would allow this account to be expanded. Accordingly, the case of bees is not extrapolated to other insects, and particular flower-visiting strategies are not presented as though these sources had demonstrated them. [1464][1479]

- Do bees feed on both nectar and pollen? | U.S. Geological Survey — Do bees feed on both nectar and pollen? Bees feed on and require both nectar and pollen. The nectar is for energy and the pollen provides protein and other nutrients. Most pollen is used by bees as larvae food, but bees also transfer it from plant-to-plan
