species produce honey, which has been appreciated by humans since ancient times. Here …

Queens play an essential role in the colonies of stingless bees. Typically, only one queen
occurs in a colony at any time, and she dominates the egg laying. Their presence maintains …

Some stingless bees are known to produce both large queens, reared from larger royal
cells, and small" miniature" queens, reared from worker cells. Here we review what is known …

Insect societies are well-known for their advanced cooperation, but their colonies are also
vulnerable to reproductive parasitism. Here, we present a novel example of an intraspecific …

How social complexity evolved remains a long-standing enigma. In most animal groups,
social complexity is typically classified into a few discrete classes. This approach is …

Phylogenetic hypotheses and estimates of divergence times have already been used to
investigate the evolution of social behavior in all lineages of bees. The interpretation of the …
