13. Long-term male aggregations of Euglossa melanotricha moure (Hymenoptera: Apidae) on fern fronds Serpocaulon triseriale (Pteridophyta: Polypodiaceae)
A communal dormitory of male orchid bees, Euglossa melanotricha Moure, was monitored over a one-year period, when they passed the night in the fronds of a Serpocaulon triseriale (Polypodiaceae) fern. The bees used the same fronds continuously, moving to neighboring fronds as senescence set in. As many as 49 males were observed together on any one night, clin

14. Orchid bees (Hymenoptera: Apidae) in the coastal forests of southern Brazil: diversity, efficiency of sampling methods and comparison with other Atlantic forest surveys
Os levantamentos da fauna de abelhas euglossíneas realizados até o momento ao longo da floresta Atlântica são restritos a poucas regiões e não permitem um entendimento mais aprofundado dos padrões latitudinais de distribuição e diversidade dessas abelhas. Por este motivo, duas áreas de floresta Atlântica do sul do Brasil, na planície costeira de

15. Forest fragments with larger core areas better sustain diverse orchid bee faunas (Hymenoptera: Apidae: Euglossina)
Male orchid bees were attracted to chemical baits and collected in nine Atlantic Forest fragments in southeastern Brazil. Fragments differed in size and shape. Three additional sites were also sampled in a nearby large fragment. Three hypothetical core areas of each fragment were measured as the total area minus an area of 50, 100, and 200-m-wide perimeter.

16. Eufriesea pulchra smith (Hymenoptera: Apidae: Euglossini): extended geographic distribution and filling gaps in Mato Grosso state, Brazil
This study was conducted in the Cotriguaçu district, situated on the bank of the Juruena River, in Mato Grosso state. The collects were carried out from August 22 to 25, 2007 with chemical baits to attract male orchid bees. The bees were captured on a daily basis, from 8 a.m. to 12 p.m. Of the 89 males captured three belonged to Eufriesea pulchra Smith. Bef

17. Diversidade e sazonalidade de abelhas Euglossina Latreille (Hymenoptera: Apidae) em duas áreas de mata estacional semidecidual no domínio do cerrado no Triângulo Mineiro. / The fauna of euglossine bees Latreille (Hymenoptera: Apidae) in two areas of Semidecidual Seasonal Forest in the Cerrado domain in Uberlândia, MG
O objetivo deste estudo foi avaliar aspectos ecológicos relacionados às abelhas da subtribo Euglossina em duas áreas de Mata Estacional Semidecidual presentes no município de Uberlândia-MG, bem como fornecer novas informações relacionadas aos padrões de distribuição biogeográfica do grupo. Os dados foram coletados entre julho de 2008 a junho de 20

18. Diversity and abundance of orchid bees (Hymenoptera: Apidae, Euglossini) in a tropical rainforest succession
Euglossine bee males are easily lured to chemical baits imitating natural fragrances gathered by bees, providing a widely applied measure for estimating the diversity and abundance of euglossines. In here, I report the composition of euglossine bees in three lowland rainforest habitats of Peru, a primary old forest, a reforested and managed forest, and a ver

19. Phenology, geographic and seasonal variation in fragrance choices and preferences of male orchid bees (Hymenoptera: Apidae: Euglossini) in Chapada dos Guimarães National Park and Província Serrana of Mato Grosso State, Brazil / Fenologia das abelhas Euglossini Latreille (Hymenoptera: Apidae) e a variação sazonal e geográfica na escolha e preferência por iscas-odores no Parque Nacional de Chapada dos Guimarães e na Província Serrana de Mato Grosso, Brasil
Orchid bees occur in the Neotropics and are known as such because the males pollinate the orchid flowers. Due to the lack of research into the Brazilian cerrado, this study aimed to report the abundance and richness of the orchid bee species found in the gallery forest of the Veú de Noiva valley in the Chapada dos Guimarães National Park and in the dry for

20. Sistematica filogenetica e biologia floral de Pogoniinae sul-americanas, e revisão taxonomica e analise das ceras epicuticulares do genero Cleistes Rich. ex Lindl. (Orchidaceae) / Phylogeny and floral biology of South American Pogoniinae, and taxonomic revision and analysis of the epicuticular waxes of the genus Cleistes Rich. ex Lindl. (Orchidaceae)
The taxonomic revision, the micromorphological and chemical study of the epicuticular waxes, as well as the pollination processes and pollinators of the genus Cleistes were reported. A phylogenetic inference within Cleistes and among genera of subtribe Pogoniinae was also established, based on morphology and nrDNA (ITS) and cpDNA (trnL-F and rps16) sequence

21. Caracterização da estrutura espaço-temporal da comunidade de abelhas euglossinas (Hymenoptera, Apidae) na Hileia Baiana
To characterize the spatiotemporal patters in species richness, abundance, and morphology of an assemblage of forest-inhabiting male euglossine, I sampled bees monthly with orchid fragrance baits in three arbitrarily selected areas of a continuous old-growth tropical coastal Atlantic forest in the Linhares Forest Preserve in southeaster Brazil. The 16,117 eu

22. Dual origin of highly social behavior among bees.
A study of behavior and structure indicates that highly eusocial behavior arose twice in the bees--i.e., in the stingless bees (Meliponinae) and in the honeybees (Apinae). Morphological features demonstrate the distinctiveness of these two groups and the relationship of the latter to bumblebees (Bombini) and orchid bees (Euglossin). The social behaviors of t
