Horizontal transfer (HT), the exchange of genetic material between species, plays important roles in transposon biology and genome evolution. In this study, we provide the first documented example of a new Academ transposon involved in recent and distant HTs into the genomes of species belonging to seven different orders of insects: Lepidoptera, Hymenoptera, Neuroptera, Embioptera, Dermaptera, Trichoptera and Zoraptera. These results suggest that HT of DNA transposons amongst insects has occurred on a broader scale than previously appreciated. The Academ transposon discovered in the Lepidoptera and parasitic wasps is of particular interest because the intimate association between wasps and their lepidopteran hosts might provide an opportunity for HT of transposons.
