• 螳螂

Dimunitive reduplication (Sun, 1999).

螳螂

1. praying mantis (Classifier: 隻／只 m c)

Either a compound of 鎌 (kama, “sickle”) +‎ 切り (kiri, “cutting; cutter”, the 連用形 (ren'yōkei, “continuative or stem form”) of verb 切る (kiru, “to cut”)), or of 鎌 (kama, “sickle”) +‎ キリ (kiri, onomatopoeia), where the kiri is imitative of the sound made by grasshoppers and katydids, and is found as a common element in the names of several insects of similar size and body shape. Compare 螽斯 (kirigirisu, “grasshopper; katydid”), 笹切 (sasakiri, “bush cricket; katydid”).

Considering the sharp forelegs of the mantis, the first derivation may be more probable.

The kanji are jukujikun (熟字訓), from Chinese 螳螂 (tángláng).
