The development of LNs during metamorphosis. a Group 1 GAL4 drivers that label both larval and adult-specific LNs. b Group 2 GAL4 drivers that label adult-specific LNs appearing before 48 h APF. c Group 3 GAL4 drivers that label adult-specific LNs appearing after 48 h APF. Projected confocal images show larval and pupal brains stained with neuropil markers DNcad (magenta). LNs were visualized by GAL4-driven mCD8GFP (green). Developmental stages are indicated by 3rd L: third instar larval and hours after puparium formation (APF): pupal stages. Arrows and arrowheads indicate pruning and re-extended processes, respectively. Asterisks denote glia, neurons that are not LNs or their processes. All ALs are oriented such that the midline is in the left. D: dorsal, L: lateral
