Brood parasitism involves the exploitation of host parental care rather than the extraction of
resources directly from hosts. We identify defining characteristics of this strategy and …

Many groups of animals have evolved social behaviours in different forms, from intimate
familial associations to the complex eusocial colonies of some insects. The subfamily …

The increasing availability of large molecular phylogenies has provided new opportunities to
study the evolution of species traits, their origins and diversification, and biogeography; yet …

Harrison's rule, that body size is positively correlated between parasites and hosts, has been
reported in a range of taxa, but whether the rule is applicable to cleptoparasitic insects is …

parasitic bees with nearly 800 species found across the globe and in nearly all …

Despite recent advances in phylogenomics, the early evolution of the largest bee family,
Apidae, remains uncertain, hindering efforts to understand the history of Apidae and …

Cleptoparasitism, also known as brood parasitism, is a widespread strategy among bee
species in which the parasite lays eggs into the nests of the host species. Even though this …
