This study describes a pollination system in a species of Araceae that involves three species of beetle, one of which is also a fruit predator. In a tropical cloud forest in Colombia, inflorescences of Xanthosoma daguense opened at dusk, releasing a sweet scent and raising their temperature 1–3 °C. Soon after, two species of Scarabaeidae (Dynastinae; Cyclocephala gregaria and C. amblyopsis) and one species of Nitidulidae (Macrostola costulata) arrived with pollen. Cyclocephala beetles remained… 
Caladium bicolor (Araceae) and Cyclocephala celata (Coleoptera, Dynastinae): a well-established pollination system in the Northern Atlantic rainforest of Pernambuco, Brazil.
TLDR
Findings of previous studies in the Amazon basin of Surinam indicated that Cyclocephala rustica is a likely pollinator of C. bicolor, which leads to the assumption that locally abundant Cyclocephalini species are involved in the pollination of this species.
The cowl does not make the monk: scarab beetle pollination of the Neotropical aroid Taccarum ulei (Araceae: Spathicarpeae)
TLDR
Comparative multivariate analysis of the floral traits of T. ulei points to a beetle-pollinated aroid, although some of the observed traits of the species are not common to other taxa sharing this pollination strategy, which might be explained by the evolutionary history of the tribe Spathicarpeae and potential pollinator shifts.
Geographic Variation and Succession of Arthropod Communities in Inflorescences and Infructescences of Xanthosoma (Araceae) 1
TLDR
Changes in composition and abundance of arthropods during the anthesis of inflorescences and in the developing infructescences of three species of Xanthosoma at three different geographic locations are reported.
Floral biology of Schismatoglottis baangongensis (Araceae) in West Sarawak, Borneo
TLDR
Low pollen/ovule ratio of S. baangongensis indicated an efficient pollination mechanism and Ester compound class floral odours, especially the dominant compounds 3-butenoic acid, 3-methyl-, methyl ester, were decisive in attracting pollinators.
Flowers are essential to maintain high beetle diversity (Coleoptera) in a Neotropical rainforest canopy
TLDR
It is suggested that the enormous diversity of canopy beetles in Amazonian tropical rainforests is due mainly to flowers and that mass-flowering trees with small white flowers of the generalist syndrome play a particularly crucial role in assembly and nourishment of this megadiverse beetle community.
Floral biology and reproductive isolation by floral scent in three sympatric aroid species in French Guiana.
TLDR
It is suggested that the different floral scents lead to clear separation of the main pollinating euglossine species, providing a directed and efficient intraspecific pollen flow that results in high reproductive success.
Pollination ecology of Monstera obliqua (Araceae) in French Guiana
TLDR
Data on pollination ecology of Araceae is still scarce and most concern species belonging to the subfamily Aroideae, which consists of unisexual flowers: female flowers are located in the lower portion and the male flowers are in the upper portion of the inflorescence.
Diversity light patterns and sex ratio of beetles of the subfamily Dynastinae Coleoptera , Melolonthidae ) arissa
TLDR
It is suggested that rainfall reduces the flight activity of Dynastinae beetles and different time schedules may be related to mating behavior, foraging behavior and the avoidance of interspecific resource competition.

Beetle pollination of Dieffenbachia longispatha (Araceae)
TLDR
Experiments demonstrate that the species is self-compatible and that fruit production is pol- experiences, suggesting that floral odors play a role as an attractant in the relationship with beetle pollinators.
Differential Importance of Beetle Species Pollinating Dieffenbachia Longispatha (Araceae)
TLDR
The proportion of the variance in fruit-set explained by beetle abundance was low for both years, suggesting that other factors contribute to female reproductive success in Dieffenbachia, or to other pollination systems where there is cumulative floral damage with increasing visitation frequencies.
The cost of mutualism: interactions between Trollius europaeus and its pollinating parasites
TLDR
These data on Trollius/ Chiastocheta interactions provide the first extensive cost/ benefit analyses for mutualism based on seed parasites as pollinators, and are rather insensitive to variation in pollinator density.
Flowering and Pollination of Philodendron melinonii (Araceae) in French Guiana
TLDR
The pollination ecology of Philodendron melinonii was studied at two locations in French Guiana and in greenhouse conditions at the Montreal Botanical Garden and the spadix temperature was measured during the entire flowering cycle.

Abstract We report a new obligate pollination mutualism involving the senita cactus, Lophocereus schottii (Cactaceae, Pachyceereae), and the senita moth, Upiga virescens (Pyralidae, Glaphyriinae) in
Pollen dispersal in Yucca filamentosa (Agavaceae): the paradox of self-pollination behavior by Tegeticula yuccasella (Prodoxidae).
TLDR
Why moths frequently deposit self-pollen to the detriment of their offspring is discussed and the yucca-yucca moth interaction with other obligate pollinator mutualisms in which neither pollinator nor plant benefit from self-pollination is compared.
Cyclocephala: visitor and probable pollinator of Caladium bicolor (Araceae).
TLDR
Observation of a small popula tion of the wellknown garden plant Caladium bicolor in Surinam found that in addition to feeding places, the plants also serve as daytime shelters and mating-sites to the beetles.
Pollination ecology of Philodendron squamiferum (Araceae)
TLDR
In French Guiana, inflorescences of Philodendron squamiferumPoepp were regularly visited by the scarab beetle Cyclocephala simulatrix Holne and (Scarabaeidae, Coleoptera) occasionally by CycloCEphala tylifera Holne, and the protogynous inflorescence exhibited features typical of beetle polli - nation.
Dynastine scarab beetle pollination in Dieffenbachia longispatha (Araceae) on Barro Colorado Island (Panama) compared with La Selva Biological Station (Costa Rica)
TLDR
The effects of selec­ tion by the local beetle populations in each locality appears to have led to the evolution of different sub-species of D. longispatha on Barro Colorado Island in Panama and at La Selva Biological Station, Costa Rica.
