It has processes spanning lobula layers 2-5B, with most synapses in layer 3 (Wu et al., 2016; Tanaka and Clark, 2022). The arbors in layers 3 and 4 contain presynaptic sites (Wu et al., 2016). Its arbors span approximately 20 optic columns, overlapping with other LC9 cells (Wu et al., 2016). Its axon fasciculates in the anterior optic tract and terminates in a dorsal and anterior glomerulus of the PVLP, medial to LC6 (Wu et al., 2016). There are around 150 cells of this type (Wu et al., 2016).
