We performed field experiments to measure the relative importance of olfactory and visual cues in nectar foraging by wild tobacco hornworm moths, Manduca sexta (Lepidoptera, Sphingidae) in the Sonoran Desert of Arizona, U.S.A. We manipulated flowers of sacred Datura (Datura wrightii; Solanaceae) to experimentally decouple floral scent from visual display and presented these cues to free-flying moths in mixed and homogeneous arrays. Moths did not feed from cloth-bagged fragrant flowers lacking… 

Synergy between visual and olfactory cues in nectar feeding by wild hawkmoths, Manduca sexta

Multimodal Floral Signals and Moth Foraging Decisions

These results highlight the importance of specific sensory modalities for foraging hawkmoths while also suggesting that they learn the floral displays as combinatorial signals and use the integrated floral traits from their memory traces to mediate future foraging decisions.

Behavioral consequences of innate preferences and olfactory learning in hawkmoth–flower interactions

Behavioral flexibility and the olfactory contrast between flowers permit the hawkmoths to persist within a dynamic environment, while at the same time to function as the major pollinator of one plant species.

Multimodal floral cues guide mosquitoes to tansy inflorescences

The data support the hypothesis that the entire inflorescence Gestalt of olfactory, CO2 and visual cues is more attractive to mosquitoes than floral odorants alone and support the previously postulated concept that haematophagy of mosquitoes may have arisen from phytophagy.

Intraspecific Combinations of Flower and Leaf Volatiles Act Together in Attracting Hawkmoth Pollinators

The results reveal a species-specific coaction between flower blend and leaf volatile background, which might provide the moth with a fine-grained analysis of food site quality.

The effect of decoupling olfactory and visual stimuli on the foraging behavior of Manduca sexta

SUMMARY Within an appetitive context, Manduca sexta, a nectivorous nocturnal hawkmoth, can be attracted by a range of stimuli including floral volatiles and visual display, carbon dioxide and water

Hawkmoths evaluate scenting flowers with the tip of their proboscis

Pollination by insects is essential to many ecosystems. Previously, we have shown that floral scent is important to mediate pollen transfer between plants (Kessler et al., 2015). Yet, the mechanisms

The role of mechanosensory input in flower handling efficiency and learning by Manduca sexta

It is found that corolla surface area negatively affects flower handling efficiency, and that reliable mechanosensory input is crucial for the moths' performance.

Context‐dependent reproductive isolation mediated by floral scent and color

It is demonstrated that indole attracts wild hawkmoths to flowers, but has little effect on the rate at which those attracted moths probe flowers, and context‐dependent behavior helps explain why these Ipomopsis species show geographical variation in the extent of hybridization and may potentially explain formation of hybrid bridges in other systems of hawkmoth‐pollinated plants.

Behavioral Responses To Multi-Modal Stimulation: The Organization Of The Foraging Instinct Of Manduca Sexta

It is found that corolla surface area negatively affects flower handling efficiency, and that reliable mechanosensory input is crucial for the moths‘ performance.



Olfactory versus visual cues in a floral mimicry system

It is found that pseudoflower fragrance can attract visitors by itself, and the ability of insects to differentiate pseudoflowers from true flowers by their fragrance may be important in the evolution of the mimicry system.

Learning, odour preference and flower foraging in moths

The results imply that moths may be discriminating among odour profiles of individual flowers from the same species, within the context of nectar foraging in moths and odour signalling by flowering plants.

Pollination by Deceit in a Mass-Flowering Tropical Tree Plumeria rubra L. (Apocynaceae)

The reproductive biology of this species differs from typical examples of floral mimicry in that Plumeria lacks a specific model, is a massively flowering tree with an extended blooming period, and may be the most abundant hawkmoth flower in tropical deciduous forest of Costa Rica during much of its bloomingperiod.

Wavelength Discrimination and the Role of Ultraviolet Vision in the Feeding Behavior of Hawkmoths1

Nocturnal Sphingidae (hawkmoth or sphinx moths) are important pollinators in tropical forests, but flower patterns reflecting ultraviolet wavelengths (that are not visible to humans) might be significant to sphingid feeding behavior.

The effect of nectar guides on pollinator preference: experimental studies with a montane herb

In all of 16 experimental replicates discrimination against albinos was reduced or eliminated after painting, and albino handling times declined toward values for blue-flowered inflorescences, indicating that an inferior nectar guide increases the energetic cost of foraging at albino.


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.

Trumpet Flowers of the Sonoran Desert: Floral Biology of Peniocereus Cacti and Sacred Datura

Night‐blooming Peniocereus cacti may benefit from sequential mutualism with the more abundant Datura species by way of pollinators nurtured as larvae byDatura foliage and as adults by DaturA floral nectar.

The combined effect of color and odor on flower choice behavior of bumble bees in flower mimicry systems

Questions that arose from the observation of flower pollination syndromes concerning signal learning and memory in hymenopteran flower visitors are explicitly asked by experimentally testing the effect of odor cues on color discrimination and generalization in bumble bees.

Sulphur-containing “perfumes” attract flower-visiting bats

In nectarivorous bats the sense of smell obviously plays an important role in searching for and localising food sources, and even single components of the scent bouquets of bat-pollinated flowers are attractive, and the preference for sulphur-containing odours seems to be innate.
