“…Overnight aggregations of bee males have been described previously for solitary bee species that exhibit site fidelity by returning to a particular sleeping roost on the successive nights (Kaiser, 1995;Alcock, 1998;Alves-dosSantos, 1999;Oliveira & Castro, 2002;Alves-dos-Santos et al, 2009). At Ribeirão Preto, the meliponary garden of the FFCLRP was daily inspected from June 03 to September 05 2010 for sleeping roosts between 17:00 h and 07:00 h. This meliponary contained approximately 150 colonies, including Scaptotrigona depilis (Moure), Tetragonisca angustula (Latreille), Frieseomelitta varia (Lepeletier), M. scutellaris (Latreille), M. quadrifasciata and Nannotrigona testaceicornis (Lepeletier).…”

“…Nothing is known about where males rest overnight after visiting such reproductive aggregations, although males of solitary bees are known to frequently spend the night on plants, alone or in groups under leaves (Kaiser, 1995;Alcock, 1998;Alves-dos-Santos et al, 2009). Furthermore, we know that solitary bee males may exhibit site fidelity by returning to a particular sleeping roost on the successive nights (Kaiser, 1995;Alcock, 1998;Alves-dos-Santos, 1999;Oliveira & Castro, 2002;Alves-dos-Santos et al, 2009). …”

Very little is known about stingless bee reproductive biology or male behaviour. In this note we provide the first observations on the male aggregations (congregation sites and roosting sites) of some stingless bee species. Our observations show that males of two stingless bee species can congregate on the same site. We also report for the first time the substrates used by stingless bee males for resting at night, that at least one species forms large sleeping roosts composed of hundreds of individuals, and that sleeping roost locations are not reused on subsequent nights.

“…This place can be small branches of plants, cavities and flowers (Kaiser, 1995;Alcock, 1998;Alvesdos-Santos, 1999;Oliveira and de Castro, 2002). Males of Ptiloglossa goffergei Moure, for example, have been observed resting during the night in bamboo trap-nests in the "Restinga" (Gaglianone MC, personal observation).…”

ABSTRACT. Males of solitary bees usually spend the night in clusters on small branches of plants, cavities and flowers. The individuals usually return to the same location each evening during their life, exhibiting site fidelity to a particular plant. We report on the sleeping roosts of the males of some oil-collecting bees of the genera Centris, Paratetrapedia, Lanthanomelissa, Monoeca, and Tetrapedia, as well as the host plants. We discuss the role of the male clusters to the associated plants.

“…Most of the knowledge about the biology of Oxaeinae is restricted to descriptions of the immature stages of certain species (Rozen 1964;Rozen and Rozen 2010) and habits other than nesting such as mating behavior, aggressive territoriality near the nests and flowers, and male aggregations in some Protoxaea and Oxaea species (Linsley and Michener 1962;Cazier and Linsley 1963;Linsley and Cazier 1972;Hurd and Linsley 1976;Alcock 1990;Oliveira and Castro 2002). Birkmann (1932) (reproduced in Hurd andLinsley 1976 andsummarized in Cockerell 1933) mentioned that Mesoxaea texana nests in large aggregations.…”

Oxaea austera nests in hard, red lateritic soils with dense grass cover. Some characters of Oxaea austera nests conform to the known architecture of the oxaeine nests such as the long, vertical shaft and the radiating, horizontal tunnels connected to vertical cells. The presence of more than one cell per lateral, cells at different depths containing larvae at different stages, and discrete walls in the main and laterals are described for the first time for Oxaeinae. One cell was located at the end of each lateral with others (2-4) near them, in some cases arranged in a row just beneath the lateral. Cells are oriented vertically and consist of a chamber, a spiral closure and an antechamber connected with a lateral. The chamber and antechamber are surrounded by a thick discrete wall. Each nest was occupied by at least two active females indicating communal nesting. They also contained older cells, suggesting the reutilization of the nests by successive generations. Both behaviors may be a response to the difficulties of excavation in hard soils. Communal nesting may be also a defensive behavior against nest cleptoparasites. The shape, size, discrete walls of lateritic soil material, spiral closure, and antechamber of O. austera cells closely resemble the fossil bee cells included in the ichnogenus Palmiraichnus from the early Eocene Asencio Formation of Uruguay. This new evidence reinforces the proposal of extinct representatives of Oxaeinae as it constructor.
