noun
scorpionfly; Japanese scorpionfly
Refers to insects of the family Panorpidae, especially Panorpa japonica. The name comes from the way the male's abdomen curls up like a scorpion's tail.
シリアゲムシはオスの尾がサソリのように曲がっている。
The male scorpionfly's tail curls up like a scorpion's.
庭でシリアゲムシを見つけた。
I found a scorpionfly in the garden.
The Japanese name しりあげむし literally means 'tail-raising insect', from 尻 (しり, 'buttocks/tail') + 上げる (あげる, 'raise') + 虫 (むし, 'insect'), describing the male's raised abdomen.
