水螳螂

水螳螂屬（學名：Ranatra）又名螳蠍蝽屬，是半翅目蠍蝽科的一類水生昆蟲。外型類似螳螂、紅娘華，雖然與紅娘華一樣以呼吸管伸出水面呼吸，但不同之處則是比紅娘華消瘦的身軀、同科但不同屬；專門吸取魚和蝌蚪等水生動物的血維生。 主要棲息於淨水域的水草叢間、池塘等等水生生物棲息地，但因水生環境汙染而數量減少。 身體區分成頭胸部與腹部兩個部分。 頭胸部有一對鐮刀般的前肢；腹部有兩對足。 尾部末端有兩根細鞭狀呼吸管形成。 本科包括以下属： Ranatra absona Drake & De Carlo, 1953 Ranatra acapulcana Drake & De Carlo, 1953 Ranatra adelmorpha Nieser, 1975 Ranatra aethiopica Montandon, 1903 Ranatra akoitachta Nieser,
