摘要

山窗螢幼蟲以扁蝸牛飼養，置於室溫下，觀察生活史和形態，結果如下：雌、雄螢卵期分別為156日及153日；幼蟲期雌螢共有六齡，其幼蟲發育期需195日（第一齡20日、第二齡24日、第三齡21日、第四齡22日、第五齡34日、第六齡75日），較雄螢共五齡為171日（第一齡21日、第二齡25日、第三齡21日、第四齡27日、第五齡75日），長39日；蛹期雌螢11日，而雄螢12日；成蟲壽命，雌螢平均16日而雄螢27日，故雄螢壽命比雌螢長。由卵至成蟲所需時間，雄螢只需335日，即可完成一世代，而雌螢需較長時間為365日，才能完成；每隻雌螢可59～152粒卵，平均122粒，文中亦探討其形態變化。

The firefly, Pyrocoelia praetexta larvae were reared on snails, Bradybaena similaris (Ferussac). A series of observation of the morphology, life history were conducted under laboratory. In laboratory-rearing experiment results were summarized as follow: The developmental period of the egg stage were 156 days for the female and 153 days for male. There are six instars in the female larval stage, the developmental period of the larval stage were 195 days, the duration of each instar 20, 24, 21, 22, 34, and 75 days respectively; whereas male larvae had five, the developmental period of the larval stage were 171 days, the duration of each instar 21, 25, 21, 27, and 77 days respectively. Pupal stage was 10-13 days, 12.4 days in average for male and 10-13 days, 11.7 days in average for female. The pupal stage was significantly longer in male than in female. The longevity of the male firefly was 18-40 days, averagely 27 days, and that of the female 12-21 days and 17 days respectively. Its' development period from egg to adult was 365 days for the female and 335 days for male. The number of eggs laid per female firefly was 123 in average. The morphology of Pyrocoelia praetexta was also discussed.
