It is a thick bundle, lateral to the longitudinal superior medial fascicle (Lovick et al., 2013). It contains the axons of DPLl2/3 lineage secondary neurons, which follow the tract established by DPLl2/3 primary neurons in the early larva and contribute to the posterior part of the adult tract (Lovick et al., 2013; Wong et al., 2013; Hartenstein et al., 2015). It also has an anterior component, formed by the DPLd posterior hemilineage secondary neurons (Lovick et al., 2013). FBbt:00049239 adult SLPad1 lineage neuron adult VLPd&p1 lineage neuron
