Omics backbone: 146 terminals including 478 taxa in total. Backbone extension: analyzed 4 source trees which contain totally 16674 internal nodes, to which 1646 taxa were assigned. Made 99 separate subtree grafts totaling 3782 terminals. Species-level: terminals with matching COI barcode for 2639 named species, single outgroup (Strepsiptera Stylops sp.). ** If used in a publication, please cite Ratnasingham and Hebert (2007) BOLD: The Barcode of Life Data System (www.barcodinglife.org).
