Thermoregulation and Heat Exchange in Euglossine Bees
Physiological Zoology, 1983The relations of the temperatures of the thorax ($T_{th}$), head ($T_{h}$), and abdomen ($T_{ab}$) to air temperature ($T_{a}$) are described for male euglossine bees attracted to baits. The large, pubescent bees in the genera Eulaema and Eufriesea regulated $T_{th}$ fairly well, as indicated by the slope of $T_{th}$ on $T_{a}$; $T_{h}$ was distinctly ...

Microsatellite loci for euglossine bees (Hymenoptera: Apidae)
Molecular Ecology Notes, 2007AbstractThe Neotropical Euglossini (Hymenoptera: Apidae) are important pollinators of many flowering plants, particularly orchids. Lack of highly polymorphic genetic markers for euglossine species has limited the study of their social organization and inbreeding.

Diploid Male Frequencies in Colombian Populations of Euglossine Bees
Biotropica, 2007ABSTRACTSome studies have recently reported high diploid male frequencies in euglossine bees indicating possible population declines. We estimated the genetic variability and frequency of males that are diploid in five Colombian species of euglossine bees using allozyme markers. Expected heterozygosities ranged from 0.10 to 0.23.

Long-term ecology of euglossine orchid-bees (Apidae: Euglossini) in Panama
Oecologia, 1987Abundance patterns during 6-7 years and orchid visitation were determined for 51 species of the 57 local euglossine bees. Male bees were counted at 3 chemical attractants presented in the same manner each month. Sites were separated by 75 km but included wet Atlantic forest at 500 m elevation, moist forest at 180 m near Barro Colorado Island, and cloud

Male Eufriesia purpurata, a DDT-collecting euglossine bee in Brazil
Nature, 1982While studying the ecology of the malaria vector Anopheles (Nyssorhynchus) darlingi Root along the Ituxi River, Amazonas, Brazil, we observed aggregates of bees on the walls of houses that were routinely sprayed with DDT. Several bees collected from DDT-treated house walls in August 1978 were identified as male specimens of Eufriesia purpurata (Moscary)

Ultrastructural characterization of spermatozoa in euglossine bees (Hymenoptera, Apidae, Apinae)
Insectes Sociaux, 2005Euglossine spermatozoa are the longest described to date for the Hymenoptera. This cell includes a head and a flagellar region. In transverse sections, the acrosome is circular at the tip but has an oval contour along most of its length. The perforatorium penetrates into a deep cavity in the nuclear tip.

Euglossine Bees as Long-Distance Pollinators of Tropical Plants
Science, 1971Euglossine bees may return to a nest from as far away as 23 kilometers in a tropical rain forest. These bees apparently forage long distances and visit the same plants repeatedly along a feeding route. They probably promote outcrossing among tropical plants with low population density; therefore, they may permit the existence of plant species whose ...
