Flower constancy in insect pollinators: adaptive foraging behaviour or cognitive limitation?
Grüter, Christoph; Ratnieks, Francis L. W.
Communicative & Integrative Biology, 2011
A synthesis of experiments on flower constancy — the tendency of an individual pollinator to visit one flower species while ignoring equally rewarding alternatives — weighing adaptive explanations against cognitive ones.

- review of flower constancy experiments
Constancy is widespread and costly, and the evidence points towards limits on switching between learned handling techniques and memories rather than towards an optimal strategy.
What it means
The authors' reading, and ours. Where they differ, that difference is the point.
How the authors put it
Flower constancy is better explained by the costs of switching between learned flower types than by it being an optimal foraging decision.
How NatureHQ reads it
This is why pollination works at all. A bee that visited a different flower species each trip would move pollen to plants that cannot use it; a bee that sticks to one species delivers pollen where it counts. The interesting part is that the behaviour plants depend on may be a *limitation* rather than a service — the bee is not being helpful, it is finding switching expensive.
- A review; the balance between adaptive and cognitive explanations is still argued.
- Most experiments use artificial flowers, which simplify handling differences.
- Constancy varies between species and with forage availability.
