白蝶（白蝶子）最有名的作品是在1957年演出台語片「呂洞賓三戲白牡丹」，該片由林楓飾演呂洞賓，白蝶則在片中飾演白牡丹，是台灣電影早期著名的古裝神話作品。白蝶近幾年參加「阿姑」周遊的獅子會社團，也是和周遊交好的演藝圈老友「33姐妹會」成員，平日幾名老友會齊聚唱歌跳舞、吃飯聊天，晚年生活十分愜意。

周遊說，上周三，好友們一如往常相約吃飯，結束後原本當周周六還有約，李朝永聯繫白蝶，但對方已讀未回，白蝶年事已高又是獨居，連續2天聯絡不到人，開始擔心，直到本周二才從家人得知白蝶已往生，但具體離世原因不得而知。

由於家屬低調，送白蝶最後一程，家屬選擇只辦家祭不辦公祭，但周遊、李朝永夫妻仍希望出席白蝶人生畢業典禮，帶領10多名獅子會姐妹們到場唱白蝶生前最愛的歌曲「思念的人」、「風吹的願望」，周遊說：「白蝶平常身體很好、很健康，跟著我們一起又唱又跳，怎麼會⋯真的很難過，看到以前照片中好多人都走了，真的太感慨。」
