Abstract Fifteen species belonging to the obscura group of the genus Drosophila were screened for sequences homologous to Drosophila melanogaster transposable elements (TEs) as an initial step in the examination of the possible occurrence of TEs at chromosomal inversion breakpoints. Blots of genomic DNAs from species of the obscura group were hybridized at three different stringencies with 14 probes representing the major families of TEs described in D. melanogaster. The probe DNAs included copia, gypsy, 412, 297, mdg1, mdg3, 3S18, F, G, I, jockey, P, hobo, and FB3. D. melanogaster TEs were not well represented in the species of the obscura group analyzed. The TEs that were observed generally exhibited heterogeneous distributions, with the exception of F, gypsy and 412 which were ubiquitous, and 297, G, Sancho 2, hobo and FB which were not detected.
