From: West Nile virus vector Culex modestus established in southern England
Phylogenetic maximum-likelihood tree of COI sequences (603 bp) from Culex modestus (North Kent Marshes (NKM) specimens in boldface) and other representatives of the Culex genus estimated using the T92+Γ+I model of nucleotide substitution, which was selected by MODELTEST. Bootstrap values are shown for the main clades only. The accession numbers and geographic origin of the 35 GenBank downloads (which represent 10 unique sequences) and COI barcodes generated in this study (asterisked) are shown. Scale bar indicates nucleotide substitutions per site.
