A maximum-likelihood phylogenetic tree of the mitochondrial cytochrome oxidase c subunit 1 (cox1) gene within a heatmap representing the degree of sharing of EVEs across samples with more than fivefold read coverage for a Ae. aegypti (n = 436) and b Ae. albopictus (n = 73). Note the 100-fold difference in scales between the trees. These results are not related to the underlying sequencing library size, and lowering minimum coverage from fivefold to onefold does not affect interpretation. Because of large number of samples, the branch labels are omitted. In a, four samples representing Aedes mascarensis from Madagascar are the first four samples after the break in the circle
