Nonfloral sources of chemicals that attract male euglossine bees (Apidae: Euglossini) [PDF]

open access: yesJournal of Chemical Ecology, 1993
We present chemical analysis of four rotten or fungus-infected logs that attracted fragrance-collecting male euglossine bees. Eight of the 10 volatile compounds detected have never been found in the fragrances of orchids pollinated by male euglossine bees.

Molecular identification of species of the Genus Euglossa Latreille (Hymenoptera: Apidae, Euglossini) [PDF]

open access: yesNeotropical Entomology, 2007
Euglossine bees interact with more than 60 plant families of the Neotropical region. The richness and abundance of these bees have been intensively studied in different ecosystems using the methodology of capturing males with chemical baits. Females are poorly known for most of the species and morphological characters for their taxonomic classification

Aspectos da biologia de Euplusia violacea (Blanchard) (Hymenoptera, Apidae, Euglossini) [PDF]

open access: yesRevista Brasileira de Zoologia, 1997
Nests of orchid bee Euplusia violacea (Blanchard, 1840) colleted in trap-nests and in the wood of a construction in Vicosa, Minas Gerais (20o45'30"S, 42o52'05"W), Brazil, were studied under laboratory condictions. Some aspects of the biology of these bees were observed, such as sex-ratio, development time, Iongevity and others.
