Sex Ratio and Nest Observations of Euglossa hyacinthina (Hymenoptera: Apidae: Euglossini)
Journal of the Kansas Entomological Society, 2007Euglossa is the largest genus of orchid bees (Hymenoptera: Apidae: Euglossini), with 103 described species from northern Mexico to Paraguay and northern Argentina (Michener 2000; Roubik and Hanson 2004). For many species of these colorful, large-bodied insects females have not been identified.

ABELHAS EUGLOSSINI EM ÁREAS SOB DIFERENTES NÍVEIS DE URBANIZAÇÃO
Anais dos Seminários de Iniciação CientíficaO crescimento acelerado das cidades contribui para a degradação do ambiente, devido a aspectos como a ocupação desordenada de áreas naturais, promovendo o desequilíbrio das comunidades biológicas (EMBRAPA, 2022), consequentemente alterando a paisagem e as interações ecológicas que normalmente ocorreriam nesses espaços (Liu et al., 2018). De modo geral,

Nesting biology and nest re-use ofEulaema nigrita (Hymenoptera: Apidae, Euglossini)
Insectes Sociaux, 1994The nesting behavior of the euglossine beeEulaema nigrita was observed in the laboratory after being transferred from three nests to observation boxes. Nests were re-used by successive generations with more than one female working in each re-use process. Associated females were always of the same generation.

Population genetic structure of orchid bees (Euglossini) in anthropogenically altered landscapes
Conservation Genetics, 2011Habitat degradation and fragmentation are widespread phenomena in tropical regions. Negative effects on the biota are numerous, ranging from interruption of gene flow among populations, to the loss of genetic diversity within populations, to a decline in species richness over time. Orchid bees (Hymenoptera: Apidae: Euglossini) are of major conservation

A new species of Exaerete Hoffmannsegg (Hymenoptera: Apidae: Euglossini) from Brazil
Zootaxa, 2006This paper describes males of a new species of the cleptoparasitic euglossine genus Exaerete Hoffmannsegg. Exaerete guaykuru Anjos-Silva and Rebêlo new species, was found in the moist forest of Planalto dos Guimarães, located in the Chapada dos Guimarães National Park in southern Mato Grosso, Brazil.

The male gonostylus of the orchid bee genus Euglossa (Apidae: Euglossini)
Zootaxa, 2006Genital characters remain unexplored in Euglossa and they could be of great value in recognizing species and understanding the phylogeny of the group as in other bee genera. We examined the external morphology of the male gonostylus in 49 species of Euglossa belonging to five subgenera and eight species groups.

Neotropical Entomology, 2012
Biogeography has been difficult to apply as a methodological approach because organismic biology is incomplete at levels where the process of formulating comparisons and analogies is complex. The study of insect biogeography became necessary because insects possess numerous evolutionary traits and play an important role as pollinators.
