The frequency of translocations in aedine chromosomal evolution appears elevated as in chironomids (aedines and chironomids belong to the suborder Orthorrhapha or lower diptera); in contrast, translocations in Drosophila (a member of the suborder Cyclorrhapha or higher diptera) have been rare (three translocations in 6400 structural changes in 300 species studied) (White 1978).
