Excision of the Mi{ET1}speckMB02738 insertion. In addition, approximately 482bp of 412 element sequence has been inserted into the original insertion site; this appears to be a gene conversion event in which the break created by the excision of Mi{ET1}speckMB02738 has been repaired from the homologous chromosome (this was a SM6a balancer carrying the 412{}881 insertion in speck2).
