The Taiwan large crow was a subspecies unique to Taiwan, exceedingly common in Tainan, Kaohsiung and the Hengchun Peninsula in the 1950s. The larvae may have subsisted on sea mangoes (Cerbera manghas) in the tropical coastal forests and mangroves, but with development and the destruction of seaside lands, the habitat and foods they depended on for survival were wiped out, and they died out in the 1960s.
「大紫斑蝶」是台灣特有亞種，1950 年代在恆春半島、高雄、台南等地極為常見，幼蟲可能以熱帶海岸林或紅樹林內的海檬果為食；但隨著濱海土地遭開發破壞，牠們賴以為生的棲地及食草被剝奪，1960 年代已滅絕。
