On Egg Eclosion and Larval Development in Euglossine Bees
American Museum Novitates, 2018 ABSTRACT This study explores egg eclosion and larval biology of orchid bees (Apidae: Euglossini) in light of existing knowledge from studies dealing with a group of tribes within the Apidae referred to as corbiculate bees. It reports that Eulaema (Apeulaema) polychroma (Mocsary) has five larval instars, and its first instar exists only briefly in that ...

More About Euglossine Bees in Amazonian Forest Fragments
Biotropica, 1991 Male euglossine bees were captured monthly for one year in modified McPhail traps baited with cineole, methyl salicylate, and skatole. The traps were operated 90 km north of Manaus, Brazil in continuous terra firme forest and forest fragments of 1, 10, and 100 ha. Of the 16 species of euglossine bees captured, Euglossa chalybeata and Eg.

Correlations Between Urban Green Areas and Euglossine Males’ Abundance [PDF]
SociobiologyGreen areas are important environments in the urban landscape where many bee species can find essential resources, such as nectar, pollen, and nesting sites.

Euglossine bees mediate only limited long‐distance gene flow in a tropical vine [PDF]
New Phytologist, 2016 SummaryEuglossine bees (Apidae: Euglossini) have long been hypothesized to act as long‐distance pollinators of many low‐density tropical plants. We tested this hypothesis by the analysis of gene flow and genetic structure within and among populations of the euglossine bee‐pollinated vineDalechampia scandens.Using microsatellite markers, we assessed ...

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests. [PDF]
New PhytolHummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Harvesting the Casualties of War: <i>Macrogerodonia peruviana</i> Rove Beetles Prey Exclusively Upon Wounded <i>Trigona</i> spp. Stingless Bees (Coleoptera: Staphylinidae; Hymenoptera: Apidae). [PDF]
Ecol EvolWe report a previously undescribed trophic interaction in which Macrogerodonia peruviana rove beetles prey exclusively on wounded or recently killed Trigona stingless bees generated during aggressive conflicts at carrion. Field observations and choice experiments showed that beetles selectively targeted injured Trigona while ignoring carrion and other ...

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen-rewarding Caribbean bloodwort. [PDF]
Am J BotAbstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Corallorhiza striata is the first example of a pseudocopulatory orchid in North America and an instance of "double deception" in fully mycoheterotrophic plants. [PDF]
Am J BotAbstract Premise Orchids have many pollination strategies, from highly species‐specific mutualisms with insects to deceit pollination, including sexual deception. The family also has the most leafless, parasitic species (mycoheterotrophs) of any plant family.
