Insects visiting the flowers of slickspot peppergrass, Lepidium papilliferum (Brassicaceae), risk predation by crab spiders, Misumena vatia (Thomisidae). In a field study conducted at two sites in southwestern Idaho, 7.5±2.7% of L. papilliferum plants (range 0-30%, N =16 surveys of up to 40 randomly selected plants) harbored a crab spider. However, through 205 minutes of observations at plants with a spider, only 15 predation attempts were observed, with only 3 of those being successful…

First report of predation on floral visitors by crab spiders on Croton selowii Baill. (Euphorbiaceae)
In the literature it has been extensively mentioned that crab spiders (Araneae: Thomisidae) prey on floral visitors of several plant species. Here we present observations of Croton selowii Baill.
ANTI-HERBIVORE PROTECTION BY MUTUALISTIC SPIDERS AND THE ROLE OF PLANT GLANDULAR TRICHOMES.
TLDR
Results indicate that Peucetia spiders are effective plant bodyguards and that when there is limited live prey they may feed on insect carcasses adhered to glandular trichomes.
Hesitation behaviour of hoverflies Sphaerophoria spp. to avoid ambush by crab spiders
TLDR
It is suggested that hesitation behaviour may be adaptive, enabling assessment of predation risk and hence avoiding ambush predators on flowers.
Biodiversity Survey of Flower-Visiting Spiders Based on Literature Review and Field Study
TLDR
This study is the first to propose the term ‘flower-visiting spiders’ and conduct a systematic investigation of their diversity, and further research is needed, especially as biodiversity is often closely linked to survey sites and ecotopes.
Seasonally variable effects of spiders on herbivory and seed production of Chamaecrista neesiana (Leguminosae Caesalpinioideae)
TLDR
Protection against herbivory by spiders in the tropical savanna is conditional on the abundance of predators over time, confirming the hypothesis that spiders may reduce herbivore abundance on vegetation, resulting in lower leaf area loss and increased fitness of plants studied.
Trait-mediated effects on flowers: artificial spiders deceive pollinators and decrease plant fitness.
TLDR
It is indicated that pollinators, mostly bees, recognize and avoid flowers with predation risk; forelimbs seem to be the predator trait recognized and avoided by hymenopterans.
The effects of predation risk from crab spiders on bee foraging behavior
TLDR
The results add to a growing body of evidence that plant--pollinator interactions are not immune to the effects of predation and suggest that the strength of such effects vary both between and within species.
Predator crypsis enhances behaviourally mediated indirect effects on plants by altering bumblebee foraging preferences

TLDR
This work used the tripartite relationship between bumblebees, predatory crab spiders and flowers to ask whether behaviourally mediated effects are localized to flowers harbouring predators, or whether bees extend their avoidance to entire plant species.
Do ambush predators prefer rewarding or non-rewarding orchid inflorescences?
TLDR
It is speculated that concealment quality of the inflorescence, the nature of the dominant pollinator(s), and/or ease of movement of spiders between inflorescences may be more important than frequency of visits by potential prey, particularly when no other form of concealment is readily available.

Crab spiders affect flower visitation by bees
TLDR
This field study is the first field study documenting negative effects of predators on flower visitation rate by pollinator populations and suggests that pollinator response to predation may influence pollinator-plant interactions.
Prey capture by the crab spider Misumena calycina (Araneae: Thomisidae)
TLDR
Crab spiders in pasture rose Rosa carolina flowers regularly attacked bumble bees, smaller bees, and syrphid flies that visited these flowers, and did not show a tendency to specialize at any time.
Insect-mediated pollination in slickspot peppergrass, Lepidium papilliferum L. (Brassicaceae), and its implications for population viability.
TLDR
The importance of pollinator diversity to the long term viability of L papillijerum is discussed and several possible explanations for this disparity in pollinator communities between sites are raised.
Prey Capture by the Crab Spider Misumena vatia (Clerck) (Thomisidae) on Three Common Native Flowers
TLDR
Spiders hunting on roses invested considerable time finding new flowers each day and also took longer to process prey than did spiders on other flowers, so bumblebees were the most important prey in terms of biomass and small syrphid flieswere the most frequently captured prey.
Predatory risk to insects foraging at flowers
TLDR
Interactions between nectar-seeking insects visiting common milkweed and their commonest predator at the inflorescences, the crab spider Misumena vatia (Clerk) (Thomisidae), were recorded.
Negative impacts of a vertebrate predator on insect pollinator visitation and seed output in Chuquiraga oppositifolia, a high Andean shrub
TLDR
The hypothesis that lizard predators can alter the behaviour of pollinators and elicit strong top-down indirect negative effects on seed output in the insect-pollinated, genetically self-incompatible lower alpine Andean shrub, Chuquiraga oppositifolia, is tested.

IDEAS A ND PERSPECTIVES Pollinators as mediators of top-down effects on plants
TLDR
The idea that predators may disrupt plant–pollinator relationships and consequently inhibit reproduction in flowering plants is explored, and experimental evidence of such an effect from a riparian system in northern California is provided.
PREDATOR EFFECTS ON AN ASSEMBLAGE OF CONSUMERS THROUGH INDUCED CHANGES IN CONSUMER FORAGING BEHAVIOR
TLDR
A foraging model is developed that predicts a predator will reduce the growth of a focal prey species at low prey density but have little effect at high prey density, and that presence of the predator will indirectly facilitate growth ofA competitor of the focal species, and this effect will be negligible at low, and maximal at high, focal species density.
