The pattern of indel formation for Helena in the D.melanogaster and D.virilis groups is very similar, suggesting a high rate of DNA loss is common in Drosophila.
Dvir\Helena is a LINE-like element. Progeny from a dysgenic cross between females of strain B9 and males of strain L160 show mobilisation of at least four different transposable elements at similar frequencies.

'Dead on arrival' copies of Dvir\Helena (transposition of Dvir\Helena generates 5' truncated copies) accumulate deletions at an unexpected high rate.
A non-LTR retrotransposable element.
