It follows the Bolwig nerve and terminates in the distal larval optic neuropil, where it outputs mainly onto visual local interneurons (Larderet et al., 2017). It dies by programmed cell death during pupal development (Jean-Guillaume and Kumar, 2022). There are approximately 8 of these per Bolwig organ (Hartenstein et al., 2019; Jean-Guillaume and Kumar, 2022). Their somas are clustered anterodorsal to those of the Rh5 photoreceptors (Hartenstein et al., 2019). Rh6 photoreceptor of Bolwig's organ Rodriguez Moncalvo and Campos (2005), show that genetic ablation or synaptic silencing of the Rh6 photoreceptor of Bolwig organ prevents the wildtype development of overlapping serotonergic arborizations. Neurotransmitter type was assessed in two ways: by double labelling of cells with an acetylcholine GAL4 driver (FBtp0014830) and a Rh6 antibody; by double labelling cells with drivers for Rh6 (FBtp0014226) and an acetylcholine antibody (Keene et al., 2011).
