Corolla stickiness prevents nectar robbing in Erica
Journal of Plant Research, 2021Floral stickiness is a rare trait with unknown function, but it is common in the mega-diverse Cape genus Erica (Ericaceae). This study investigated the role of stickiness measured as adhesive strength in Erica as protection against nectar robbing and its correlation with floral traits.

Honeybees with extensive foraging experience rob nectar more frequently
The Science of Nature, 2021Not all flower-visiting animals act as pollinators; some visitors engage in foraging nectar without pollen transfer. The tendency to rob nectar is related to visitors' morphological traits and rewards per foraging effort, and drivers of this variation within visitor species are largely unknown.

Variation in nectar robbing over time, space, and species
Oecologia, 2002Spatiotemporal variation in the interactions among plants and animals is widespread; yet our conceptual and empirical understanding of this variation is limited to a few types of visitors, mainly herbivores, pollinators, seed predators, and seed dispersers. Despite the ubiquity of nectar robbing and the strength of its effects on plant fitness, we know

NECTAR-ROBBING BUMBLE BEES REDUCE THE FITNESS OFIPOMOPSIS AGGREGATA(POLEMONIACEAE)
Ecology, 1999The removal of floral nectar by nectar robbers may change the behavior of legitimate pollinators and, consequently, the pollination and fertilization success of flowering plants. We measured the effects of a nectar-robbing bumble bee, Bombus occidentalis, on male and female reproductive success of Ipomopsis aggregata (Polemoniaceae).

Nectar robbing impacts pollinator behavior but not plant reproduction
Oikos, 2016Trait‐mediated indirect effects (TMIEs) refer to interactions in which the effect of one species on another is mediated by the behavior of a third species. A mechanistic approach that identifies the direction and impact of TMIEs can shed light on why different net outcomes are observed in the same general phenomena across systems ...

Effects of nectar-robbing on plant reproduction and evolution
Frontiers of Biology in China, 2007The relationship between plant and pollinator is considered as the mutualism because plant benefits from the pollinator’s transport of male gametes and pollinator benefits from plant’s reward. Nectar robbers are frequently described as cheaters in the plant-pollinator mutualism, because it is assumed that they obtain a reward (nectar) without providing

The behavioral ecology of nectar robbing: why be tactic constant?
Current Opinion in Insect Science, 2017How do animals forage for variable food resources? For animals foraging at flowers, floral constancy has provided a framework for understanding why organisms visit some flowers while bypassing others. We extend this framework to the flower-handling tactics that visitors employ. Nectar robbers remove nectar through holes bitten in flowers, often without

Nectar Robbing and Pollination of Lantana camara (Verbenaceae)
Biotropica, 1976Floral robbers are categorized as nectar-foraging, nectar-foraging-perforating, and pollen-foraging. Trigona fulviventris is a nectar-foraging-perforating robber of yellow flowers of Lantana camara. Flower head maturation of L. camara is centripetal and flowers turn from yellow to reddish-orange, resulting in inflorescences of central yellow flowers ...
