成蟲在伐倒木、新剝皮的原木和濕板材上鑽圓形深約5mm的侵入孔,然後順年輪方向開鑿長約15-20cm的母坑道,隨即將蛀屑推出坑道。雌蟲產卵於母坑道壁的小室中,並一直守衛在母坑道中直到死亡。幼蟲坑道甚密,縱向排列,充塞粉狀排泄物;深約1. 5cm,最深3cm,全長約10-15cm。新成蟲羽化後就地補充營養,蛀出若干小孔,排出大量蛀屑,被害木材僅留一層薄外皮,一觸即破。

Miwa (1943)曾記錄此種為柑橘樹(Citrus sp.)、棉花(Gossypium arboreum L.)的害蟲。中國則曾記錄油茶(Camellia oleifera Abel)、櫟屬(Quercus sp.)、辣椒(Capsicum annuum L.)為其寄主。在日本,則記錄此種成蟲、若蟲取食苦楝(Melia azedarach L.);另一筆記錄則是在苧麻(Boehmeria nivea (L.))上發現。筆者所檢視的標本中,係友人侯舜為先生在馬拉巴櫟(Pachira macrocarpa (Schltdl. & Cham.) Walp.)上採得一隻雌性個體。
