The ambrosia beetle, Xylosandrus discolor (Blandford) (Scolytinae: Curculionidae), is common in southeastern Asia. As this beetle bores into wood and reproduces, its only food source is the white fungi (cover the chamber in the figure) which are cultured by the adult. Xylosandrus ambrosia beetles each have a pronotal mycangia (an open void in the body) which transport ambrosia fungi from their natal gallery to their new gallery. Mycangia are dynamic and their morphological changes correspond to the phases of the symbiosis (see pages 732–742). Photo provided by You Li.
