黃緣螢為本省產之水生螢火蟲,成蟲壽命平均約10天,蛹期平均約7天,幼蟲
期平均約90天,卵期平均約25天,完成一個世代平均約120天 。幼蟲以螺為
其天然食物,至少有十種以上之小型螺類,可被幼蟲捕食。老熟幼蟲會登
陸,築土室化蛹 。平均每一雌蟲產下約100粒卵。以玻璃製水族缸配上打
氣幫浦及照明設備等裝置 ,並以河螺為食物飼育幼蟲 。飼育環境將水溫
控治在22.5±2.5℃,光週期為 L:D =14:10之狀況下,以各齡幼蟲之大約體
長及前胸背板長寬,判斷齡期 ,以了解幼蟲生長狀況 。飼育80天後檢視幼
蟲之存活率,淺水型飼育缸之幼蟲存活率為94.6﹪,深水型飼育缸之幼蟲存
活率為91.2﹪ 。以幼蟲飼育至50﹪羽化成蟲計之,淺水型飼育缸之飼育日
數為148天 ,而深水型飼育缸之飼育日數為167天 。採動物性蛋白達50﹪
以上,其餘為脂肪、葡萄糖、維生素 、太白粉及糯米粉配置成一種人工飼
料。以塑膠水盤為飼育容器加上打氣幫浦供飼養幼蟲。試驗結果顯示,幼
蟲期完全用人工飼料,將幼蟲飼育至50﹪羽化成蟲數之飼育日數為208天。
此人工飼料在飼養4-6齡幼蟲較1-3齡為佳 。

Luciola ovalis Hope is one of the aquatic fireflies commonly
distributed in Taiwan. Based on the present obervations by
ficial rearing, its adult longevity was found to be ca. 10
days; pupal period, ca. 7 days; larval stage, ca. 90 days and
egg period, ca. 25 days. It took about 120 days to complete the
whole life cycle. The larvae could feed on at least 10 smallils
as their food. The matured larvae climbed up from water to the
ground for pupating in a soil chamber. Each female could lay
about 100 eggs in her life. Artificial rearing of the firefly
with a river snail was carried out in a glass tank equipped
with an air pump andting lamps. The rearing conditions were set
up at 22.5 ±2.5℃, water temperature; and L:D=14:10,
photoperiod. Each instar was judged by measuring body length
and prothorax length and width of the reared larvae. The larval
survival was recorded 80s after rearing and was found to be
94.6% by the shallow rearing tank and 91.2% by the deep tank.
The period for 50% adult emergence was 148 days by the shallow
tank and 167 days for the deep one. An artificial diet was
developed for rearing this firefly. The diet is composed of
above 50% animal proteins to which were added fat, dextrose,
vitamins, starch and sweet rice powder. The rearing on this
diet was conducted in a plastic tray equipped with an air pump.
The results showed that the larvae took 208s to reach 50% adult
emergence. This artificial diet wasfor rearing 4th to 6th
instar larvae than for 1st to 3rd instars.
