Phylogenetic tree of hymenopteran CYP4 genes. Branches where statistically significant positive selection was found by Z-test are in red. Positive selection was found in most of the terminal branches of the phylogenetic tree. Many lineage-specific duplications are evident in N. vitripennis, C. floridanus and C. biroi
