It develops from the larval corpus cardiacum, which migrates posteriorly during metamorphosis (Dai and Gilbert, 1991). It is located ventral to the corpus allatum, dorsal to the esophagus and anterior to the proventriculus and it forms a complex with the hypocerebral ganglion (Nassel and Zandawala, 2020). It is connected to the brain by the nervi corporis cardiaci, which carry axons of secretory neurons that release neuropeptides in this location (Dirksen et al., 2008). It also produces Adipokinetic hormone and Limostatin (Lee and Park, 2004; Nassel and Zandawala, 2020). adult hypocerebral ganglion corpus cardiacum adult retrocerebral complex
