with fully worn mandibles and wings. Probably these females had been the founders of the nests, and the other bees were their daughters, which remained in the natal nest. The presence of females of two generations may indicate eusocial behaviour, although division of reproductive labour could not be confirmed. I believe these newly emerged daughters would not have helped their mother to produce a second generation, because the nests were studied at the end of the warm season in Patagonia (beginning of February) when few flowers remain in the field. Considering also that no larvae or pupae were found in the nests and that the first males appear in the field approximately by mid-December (in

, Table S14), I infer that these bees were going to spend the winter as inseminated females, in their natal nests. The following spring these females might either found their own nest or re-use their natal nest. Unfortunately, data are insufficient to conclude whether this species is solitary or social, but it is univoltine in the area studied.
