ITmD37E, a unique class II transposable element (TE) with an ancient origin, appears to have been involved in multiple horizontal transfers mosquitoes as ITmD37E sequences from 10 mosquito species of five genera share high nucleotide (nt) identities. For example, Aedes aegypti and Anopheles gambiae, which estimated common ancestor 145-200 million years ago, display 92% nt identity. The comparison host phylogenies shows lack congruence. wide distribution conserved ITmD37Es the presence intact copies suggest that this may recently active.
