DNA sequence of three Dhet\Uhu isolates has been determined, and compared to sequences from four other Hawaiian species, D.silvestris, D.differens, D.planitibia and D.picticornis, and D.melanogaster. The element arose at least 5Myr ago, at the time of divergence of D.picticornis from the other species examined. Uhu elements may have been transmitted vertically and that transposition may have been activated at the time of the formation of each species as it colonized the newly formed islands of the Hawaiian archipelago.
