“…siqueira-filho & Machado (2001) noted that this flowering strategy consists of producing just a few flowers per day during a long period of time, which favors random cross-pollinations between individuals of different groups. a study by Lenzi & orth (2011) with O. monacantha in restinga areas on florianópolis Island demonstrated that the flowers of this species are frequently visited by different bee guilds and indicated that Cephalocolletes isabelae urban, 1995 (colletidae) is an oligolectic floral visitor and the principal pollinator of O. monacantha.…”

-(Mixed reproduction systems in Opuntia monacantha (cactaceae) in southern Brazil). the cactaceae have morphological and physiological adaptations associated with their life histories that are reflected in different modes of reproduction and multiplication. the reproductive phenology, preferential reproductive mode, and the sexual and asexual multiplication of Opuntia monacantha were investigated between 2003 and 2006 in two restinga (sandy coastal) environment in southern Brazil to determine the adaptive values of its reproduction modes. flowering was annual and occurred continuous for approximately 100 days between the months of September and January, with a few flowers opening per day per individual (but many in the whole population). Facultative xenogamy was identified as the preferential sexual system, with the highest levels of fruit and seed formation following natural pollination. the seeds are recalcitrant and have high germinative capacities under laboratory conditions. Seedling recruitment and establishment in the field was extremely reduced. The skins of the fruits and the cladodes have high capacities for regeneration and clonal multiplication because of their areolas.

“…The flowers are visited by insects such as bees, ants (Hymenoptera), and beetles (Coleoptera). The floral resource offered is pollen; nectar is absent (Lenzi & orth 2011). The hundreds of white stamen filaments each have yellow sagittate anthers.…”

“…For example, Cyclocephala species are known to destructively feed on flowers of some crop plants (Remillet 1988, Posada Ochoa 1989) and the cactus species Echinopsis ancistrophora Speg. (Schlumpberger et al 2009) and Opuntia monocantha Haw (Lenzi and Orth 2011). …”

The cyclocephaline scarabs (Scarabaeidae: Dynastinae: Cyclocephalini) are a speciose tribe of beetles that include species that are ecologically and economically important as pollinators and pests of agriculture and turf. We provide an overview and synopsis of the 14 genera of Cyclocephalini that includes information on: 1) the taxonomic and nomenclatural history of the group; 2) diagnosis and identification of immature life-stages; 3) economic importance in agroecosystems; 4) natural enemies of these beetles; 5) use as food by humans; 6) the importance of adults as pollination mutualists; 7) fossil cyclocephalines and the evolution of the group; 8) generic-level identification of adults. We provide an expanded identification key to genera of world Cyclocephalini and diagnoses for each genus. Character illustrations and generic-level distribution maps are provided along with discussions on the relationships of the tribe’s genera.

The adult scarab beetle fauna of the canopy in a lowland tropical rainforest in southern Venezuela was observed and collected by means of a 42-m-tall tower crane for a complete year. This first census of an entire Amazonian canopy scarab community was embedded within the interdisciplinary research project "Towards an understanding of the structure and function of a Neotropical rainforest ecosystem with special reference to its canopy" organized by the Austrian Academy of Science. The Scarabaeidae represented one of the most species-rich beetle families in the canopy of the crane plot and were therefore selected for a detailed analysis of host-use patterns. Thirty-three species of Scarabaeidae with 399 individuals were recorded, including two species represented by singletons. Subfamilies abundant in the canopy were the Rutelinae, Dynastinae, and Melolonthinae. Species were diurnal or nocturnal flower visitors restricted in their occurrence to their host trees during the flowering season. The scarab beetles remained commonly on one host tree species throughout the entire flowering period and switched to another host tree species only after depletion of food resources. Some species fed on extrafloral nectar but feeding on fruits and leaves was uncommon in the observed species. Most species showed a broad host range, often with abundant species recorded on several host trees. Seven species were found exclusively on one tree species. The co-occurrence of up to five congeneric species sharing the same host trees and diet was conspicuous. With this study, it could be shown how species of Scarabaeidae track available food resources within the canopy of a tropical rainforest.
