Following publication of this work , it was brought to our attention that seven of the mitochondrial COI haplotypes described in this manuscript as Spodoptera exempta haplotypes were in fact other species. These have been identified as Amyna punctum complex (haplo2), Chrysodeixis acuta (haplo4), Spodoptera triturata (haplo5), Vittaplusia vittata (haplo13), Condica sp. (haplo14) and Mesogenea varians (haplo15 and haplo16). As a result, we cannot now support one of our original conclusions suggesting that the Spodoptera genus does not appear to be monophyletic. The text describing and discussing this claim in the
original manuscript  should be disregarded. However, it should be clearly stated that the main findings of the article, namely that the presence of Wolbachia appears to be driving a mitochondrial selective sweep within S. exempta, still holds true. Indeed, new analysis strengthens the extent of the skew. Here we present the results of the re-analysis with the corrected data sets along with revisions of the relevant figures.
