Distribution of haplodiploidy in the phylogeny of 76 arthropod species. The tree is based on the time tree of Thomas et al. [32]. Hymenopterans are colored in green; non-Hymenoptera species are colored in blue; diploid species are in red. Different types of haplodiploidy are in parenthesis. Names of major arthropod orders with more than one species in the tree are next to the corresponding clade
