In the embryo, one of these cells can be found in each hemisegment from S1-A8 (Birkholz et al., 2013; Urbach et al., 2016). In the larva, it resumes proliferation in segments S3 to A1 (Lacin and Truman, 2016). The neurons that develop from this neuroblast after larval hatching form postembryonic lineage 23, which has its cell bodies located laterally, just ventral to the neuropil (Birkholz et al., 2015; Lacin and Truman, 2016).
