Figure 1.

Neighbour-Joining tree including 45 Culicidae species recorded in Belgium and in the Netherlands based on COI (K2P; 658 bp fragment; 2721 barcodes (including the three newly generated sequences)). The bootstrap values (BS; 500 replicates) are shown in the tip labels for the collapsed sequence clusters, while they are displayed at the branch points for the non-collapsed species (sequences of query specimens highlighted in grey). Clusters were collapsed to make the overall tree visually clearer. Minimum bootstrap displayed is 75, other branches are collapsed.
