With Chang's help, however, Kuo was able to take a complete series of pictures of the butterfly from the egg to the adult which were published in the journal of the Japanese Society of Lepidopterists.
可惜的是，照片效果不佳，幾乎看不出是什麼東西。幸好張保信先生不但養蝶，還有一套完整的昆蟲攝影裝備。便又找來蝶卵，重新自行飼養，並且拍下了蝶卵詳細的孵化過程。後來以兩個人的名字共同在日本的鱗翅學會所出的刊物上正式發表。
