印度大田鱉（＂Lethocerus indicus＂ (Lepeletier & Serville, 1825)）和狄氏大田鱉（＂Kirkaldyia deyrolli＂ (Vuillefroy, 1864)）為台灣現存兩種稀有大型水棲昆蟲，本研究擬以採自苗栗地區之印度大田鱉卵塊，在實驗室藉由人工飼養，建立此蟲各齡期之基礎生活史及相關生物學資料。本研究結果顯示，在25℃水溫條件下，此蟲一至五齡若蟲之蟲期分別為5、7.3、10.9、10.8與20.2天。本研究並記錄實驗室中卵塊孵化率、各齡若蟲存活率與形質測量及相關行為。

＂Lethocerus indicus＂ (Lepeletier&Serville, 1825) and ＂Kirkaldyia deyrolli＂ (Vuillefroy, 1864) are both rare aquatic insects in Taiwan. In this study, we reared the egg spawn of ＂L. indicus＂, collected from Miaoli County in an artificial environment. We recorded each nymph instar and all related information. We found that the duration of the various instars of ＂L. indicus＂ under a 25℃ environment were 5, 7.3, 10.9, 10.8, and 20.2 days, respectively. We also recorded the measurements of the external morphological characters of the nymphs and the adults, and the morphological data and images were documented for further comparative study.
