The number of Tirant insertion sites in the Dsim euchromatic genome varies between populations, ranging from 0-5, although some Tirant sequences are present in the heterochromatin of most populations.
Tirant sequences are present in species from the melanogaster and obscura groups. Data suggests that ancestral sequences of Tirant appeared after the Sophophora radiation and before the divergence of these groups.
