Numbers following the ME and LO represent the layer numbers in which the neurons arborize. # and ## show that the neuron arborizes only in the anterior (#) and posterior (##) part of the dACA, respectively. Asterisks represent that the neurons which innervate only in the dorsal three-quarters (*), ventralmost (**), or ventral half (***) of the lobula or medulla were observed. AL, antennal lobe; AME, accessory medulla; ATL, antler; CA, main calyx; AVLP, anterior ventrolateral protocerebrum; dACA, dorsal accessory calyx; FLA, flange; GNG, gnathal ganglia; ICL, inferior clamp; lACA, lateral accessory calyx; LH, lateral horn; LO, lobula; mALT, medial antennal lobe tract; ME, medulla; mlALT, mediolateral antennal lobe tract; OL, optic lobe; OLCT, optic lobe calycal tract; PB, protocerebral bridge; PLP, posterior lateral protocerebrum; PRW, prow; SCL, superior clamp; SCT, subesophageal calycal tract; SLP, superior lateral protocerebrum; SMP, superior medial protocerebrum; SPS, superior posterior slope; vACA, ventral accessory calyx; WED, wedge.
