Figure 6. Phylogenetic trees from analyses of four nuclear genes for representative taxa of the four major holometabolous insect orders.

Sequences for the analysis of wingless, PEPCK, and ArgK were obtained from the NCBI database, the 18S dataset represented a reduced dataset from the analysis of Whiting (2002) that was supplemented with some additional taxa of Apidae from the NCBI database. Hymenopteran taxa are highlighted by yellow branches.
