Abstract We examined the genomic occurrence of the transposable elementpogo in over 120 strains ofDrosophila melanogaster, from around the world and from different eras. All had multiple copies of a 2.1 kilobase (kb)pogo element, and multiple copies of several size classes between 1.0 and 1.8 kb. There were differences between strains in intensities or presences of deletion-derivative size classes, suggesting current or recent mobility in the species. We were unable to find anypogo-hybridization in eight other species in the genus, in three subgenera, or in the relatedScaptomyza pallida. Thepogo element may be a ‘middle-aged’ element in the genome ofD. melanogaster, having entered the species since its divergence from its sibling species, but long before theP andhobo elements.
