General Information
Term third segment of antenna ID (Ontology) FBbt:00004515 (Fly Anatomy)
Definition Largest segment of the antenna. It is bulbous, light grey in color and it bears numerous hairs and sensilla, including trichoid, basiconic, intermediate and coeloconic sensilla. It has an articulated joint with the second segment of the antenna. It contains the sacculus.[ FlyBase:FBrf0007734 FlyBase:FBrf0031004 ]
