The CA-CC (corpora allata-corpora cardiaca) complex. The CC is usually milky colored, while the CA is round and clear (the photo here shows more white color due to lighting conditions). CA is the source of juvenile hormone, which regulates division of labor in adult workers. CC stores PTTH (prothoracicotropic hormone) and release it when needed, therefore called a neurohemal organ.
