earwig

earwig: [OE] A colloquial Old English term for ‘insect’ was wicga (which would have been pronounced something like ‘widger’). It probably came from the same prehistoric Germanic base (*wig-) as produced English wiggle [13], and so is roughly equivalent in spirit to modern English creepy-crawly. There used to be a belief (perhaps still is) that earwigs creep into people’s ears and penetrate inside their heads, and so the Anglo-Saxons called them ēarwicga, literally ‘ear-insect’. The same notion lies behind French perceoreille, literally ‘pierceear’, and German ohrwurm, literally ‘earworm’, both of which stand for ‘earwig’.

earwig (n.)

type of insect (Forficula auricularia), Old English earwicga "earwig," from eare (see ear (n.1)) + wicga "beetle, worm, insect," probably from the same Germanic source as wiggle, on the notion of "quick movement;" perhaps distantly related to PIE root *wegh- "to go." So called from the ancient and widespread (but false) belief that the garden pest went into people's ears. Compare French perce-oreille, German ohr-wurm. A Northern England name for it reported from 1650s is twitch-ballock.
