The Orchid Bee Fauna (Hymenoptera: Apidae: Euglossini) of a Neotropical Savanna: an Efficient Protocol to Assess Bee Community and Diversity Along Elevational and Habitat Complexity Gradients.

Males of euglossine bees, also known as orchid bees, are attracted to aromatic compounds and this feature has been exploited to collect them. Here we sampled orchid bee males using a rapid passive method in a Neotropical savanna ecosystem in Rio Preto State Park (PERP), southeastern Brazil. The sampling protocol consisted of 5-day surveys using scent traps at the beginning and end of the rainy seasons.
