Nepa (genus) : ウィキペディア英語版 | Nepa (genus)
''Nepa'' is a genus belonging to the family Nepidae, known as water scorpions. They are oval-bodied, aquatic insects with raptorial front legs. Like other members of the Nepidae, they have a pair of nonretractable cerci-like breathing tubes on the terminal abdominal segment, a characteristic which readily distinguishes them from the Belostomatidae. Their primary staples are other insects and small aquatic vertebrates. They can inflict a painful bite when handled. ==Etymology== 'Nepa' is a classical Latin word for a 'scorpion' or 'crab'.〔('Nepa' ) on (latin-dictionary.net )〕
