Characteristics of the TEs horizontally transferred between insects. Minimum numbers of transfer events are given in parentheses. The “Other” categories comprise all superfamilies of a given class of TEs [DNA transposons (class II) or retrotransposons (class I)] involved in <15 HTTs each. TE families (Left) correspond to those retrieved using RepeatModeler (Dataset S2). Center represents the mean fraction of an insect genome that is constituted by TEs from these families, which belong to a given super family.
