Caffeinated Forage Tricks Foraging Honeybees/ Curr. Biol., Oct. 15, 2015 (Vol. 25, Issue 21)

Caffeine, which is found naturally in some nectar, causes the honeybees to overestimate the quality of the forage, which leads to increased foraging and recruitment to that resource, even though equal-quality forage is also available. Ultimately, caffeine in nectar may benefit not the bee, but the plant, by giving the plant a way to manipulate its pollinator, showing that conflict exists, even amid a (mostly) cooperative mutualism.
