Functional morphology in male euglossine bees and their ability to spray fragrances (Hymenoptera, Apidae, Euglossini)

Abstract – An unpredicted occurrence of the cleptoparasitic orchid bee Aglae caerulea is announced for the Pantanal wetland biome in midwest Brazil, cataloged in a gallery forest in

Two types of secretion are observed in win- ter bees: (1) the secretion around the end appa- ratus, which is probably the same as that observed in summer bees, and (2) electron

Thus, behavioral observations followed by kinship analysis can provide better estimates of reproductive skew rate in all types of associations between reactivating females, to ver-

Abstract – In this study, both the genetic diversity and population genetic structure of Eufriesea violacea from six Atlantic Forest fragments, located in four Brazilian states,

Normally, these struc- tures are found only on the females but in two clades of Neotropical oil-collecting bees, Tetra- pediini and Tapinotaspidini (both Apidae: Apinae), the fore

anthidioides and two populations with continuous tergal stripes, one from northern Minas Gerais another from Sergipe and northeastern Bahia, ranging from São Paulo up to the

When we analyzed the dendrograms of morpho- logical similarity, built based on the Mahalanobis and Procrustes distances for all samples of the two species, we also found the

In this sense, the current study aimed to survey the richness, abundance and diversity of orchid bees in three different phytophysiognomies of the Brazilian Atlantic Forest in
