Many insects foraging for nectar or pollen exhibit flower constancy, a learned fidelity to a particular species of plant that previously provided a reward. Constancy may persist even when alternative flowers are available that provide a greater or less variable reward. This strategy entails more travelling time than one of generalization (visiting all suitable flowers as they are encountered). The consensus at present is that this increase in travelling time is offset by decreases in handling…

Can flower constancy in nectaring butterflies be explained by Darwin’s interference hypothesis?
TLDR
Darwin’s interference hypothesis remains a valid explanation for flower constancy in foraging butterflies, and savings in handling time resulting from constancy must exceed increases in travelling time necessitated by ignoring other suitable species.
Flight Durations in Bumblebees Under Manipulation of Feeding Choices
TLDR
The results suggest that bees indeed save time though flower-constant foraging but that this time savings is a small (∼1 s/flower visit) under laboratory conditions, and appears only when switches between flower types are infrequent.
Foraging strategies of insects for gathering nectar and pollen, and implications for plant ecology and evolution
TLDR
This review attempts a synthesis of the recent literature on selectivity in pollinator foraging behaviour, in terms of the species, patch and individual flowers that they choose to visit, so that foragers can respond to the pattern of rewards that they encounter.
Why do pollinators visit proportionally fewer flowers in large patches
TLDR
Data on the payoff curve achieved by bumblebees when visiting patches containing different numbers of inflorescences are presented, and the marginal value theorem is used to predict the optimum duration of stay within patches to demonstrate that visiting a declining proportion of inflorescence as patch size increases is an optimal strategy.
Flower use of the butterfly Maniola jurtina in nectar‐rich and nectar‐poor grasslands: a nectar generalist with a strong preference?
TLDR
By means of behavioural tracking, foraging patterns of Maniola jurtina butterflies in nectar‐rich and nectar-poor grasslands are identified and a significant preference for a few nectar sources in a context‐dependent way is shown.
Flower constancy in the hoverflies Episyrphus balteatus (Degeer) and Syrphus ribesii (L.) (Syrphidae)
TLDR
It is argued that constancy in these syrphids is unlikely to result from learning constraints on handling ability, currently the most widely accepted explanation for flower constancy, because they forage primarily for pollen which is easily located in most flowers they visit.
Adaptive Foraging of Pollinators Can Promote Pollination of a Rare Plant Species
TLDR
An individual-based model of pollinator foraging economics is used to predict how visitation rates and pollination success of two coflowering plant species change with their frequency (relative abundance).
Foraging responses in the butterflies Inachis io, Aglais urticae (Nymphalidae), and Gonepteryx rhamni (Pieridae) to floral scents
TLDR
Investigating foraging responses to floral scents in three temperate butterfly species suggests that these butterflies use floral scent as an important cue signal to initially identify and subsequently recognize and distinguish among rewarding plants.
Adult butterfly feeding–nectar flower associations: constraints of taxonomic affiliation, butterfly, and nectar flower morphology
TLDR
It is suggested that small size and short proboscises could give them a competitive advantage for exploiting nectar in such situations and be of significance for conservation.

Learning constraints and floral choice behaviour in bumble bees
TLDR
The results suggest that when bees forage on an increasing number of floral types, their ability to discriminate between these and non-rewarding types is reduced considerably.
Flower constancy and learning in foraging preferences of the green‐veined white butterfly Pleris napi
TLDR
The mechanisms underlying flower choice in the butterfly, Pieris napi (L.), are assessed, enabling butterflies to avoid flower species which experience has shown are poor sources of nectar, and to adapt to temporal and spatial changes in nectar availability.
UNCERTAINTY AND POLLINATOR-PLANT INTERACTIONS: THE FORAGING BEHAVIOR OF BEES AND WASPS ON ARTIFICIAL FLOWERS'
TLDR
Analysis of the sequence of visits made by individual forages seems to indicate that bees learned to distinguish the variable floral type during the foraging bout, which would suggest a more general model of foraging behavior in variable environments.
THE FORAGING SPECIALIZATIONS OF INDIVIDUAL BUMBLEBEES
TLDR
The foraging behavior of bumblebees is discussed from a comparative standpoint with other bees and in relation to food distribution and availability in the environment.
Nectarivore foraging ecology: rewards differing in sugar types
TLDR
The results suggest that optimal foraging theory (maximization of net caloric gain per unit time) is a robust predictor of behaviour with regard to the sugar types common to nectars; such optimal foraged is, however, limited by a superstructure of individual constancy.
Memory Constraints and Flower Choice in Pieris rapae
TLDR
In laboratory tests, Pieris rapae, the cabbage butterfly, showed flower constancy by continuing to visit flower species with which it had experience, and the time required by individuals to find the source of nectar in flowers decreased with successive attempts, the performance following a learning curve.

HONEY BEE FORAGING ECOLOGY: OPTIMAL DIET, MINIMAL UNCERTAINTY OR INDIVIDUAL CONSTANCY?
TLDR
Experiments using honey bees and artificial flower patches were designed to test three alternative foraging ecology models: optimal diet, minimal uncertainty, and individual constancy, which found each bee was constant to one colour, even though that behaviour often failed to maximize reward or minimize uncertainty.
