臺灣產邊褐端黑螢之生活史特性與分布

邊褐端黑螢(Abscondita terminalis)是農田間常見的螢火蟲之一，主要分布於臺灣西部低海拔地區果園、休耕農田及草生地等棲地。本研究自苗栗縣獅潭鄉採集雌蟲回研究室進行採卵，卵孵化率可達98.9% (n=90)；孵化後一齡幼蟲單隻飼育，以舉尾蟻餵食，共60組，最終45隻羽化成功，羽化成功率75%，完成一世代平均361.2 ± 26.0天；其中卵期平均21.0 ± 3.2天，幼蟲期平均318.0± 26.6天，土繭期平均1.0 ± 0.0天，蛹期平均8.0 ± 1.5天，成蟲期平均13 ± 4.5 天(n=45)；雄蟲完成一世代平均345.6 ± 13.6天(n=13)，雌蟲完成一世代平均367.6 ± 27.2 天(n=32)，比較雄蟲與雌蟲一世代之日數有顯著差異(t=-2.759, p ＜0.05)；每隻雌蟲平均產卵量99.9 ± 45.0粒(n=26)。本種在臺灣的分布包括新北市、桃園市、新竹縣、苗栗縣、臺中市、南投縣、嘉義縣及屏東縣等地，約呈零星分布。

Abscondita terminalis is one of the common fireflies in the field, and it mainly occurs in orchards, fallow farmlands, and low-altitude habitats of western Taiwan. Females were collected from Shitan Township, Miaoli County. The egg hatching rate in the laboratory was 98.9% (n = 90). 60 hatched larvae were fed with mixtures of Crematogaster spp. (Hymenoptera: Formicidae) for rearing, of which 45 individuals emerged successfully (75%). One generation lasted 361.2 ± 26.0 days, including 21.0 ± 3.2 days in the egg stage, 318.0 ± 26.6 days in the larval stage, 1.0 ± 0.0 days in the soil, 8.0 ± 1.5 days in the pupal stage, and 13 ± 4.5 days in the adult stage (n = 45). The generation time was 345.6 ± 13.6 days (n = 13) in males and 367.6 ± 27.2 days (n=32) in females, with a significant difference (t-test, t=-2.759, p ＜0.05). One female laid 99.88 ± 45.04 (n =26) eggs on average. This species was recorded in New Taipei City, Taoyuan City, Hsinchu County, Miaoli County, Taichung City, Nantou County, Chiayi County, and Pingtung County, but with a fragmented distribution and a sporadic occurrence.
