قَدُوحٌ

and
أَقْدَحُ, (K,) or
قَدُوحٌ أَقْدَحُ, (A,) (tropical:) The ذُبَاب [i. e. common fly, or flies]: (A, K, TA:) which one never sees otherwise than as though producing fire with the two fore legs [by rubbing them together like as one rubs together the زَنْد and the زَنْدَة]. (TA. [But in a verse cited by Meyd in his Proverbs, instead of القدوح
الاقدح, we find القَدُوح الأَقْرَح; and he says that الأَقْرَحُ (q. v.) is from القُرْحَةُ, and that every ذُبَاب has upon its face a قُرْحَة (or white mark): see that verse in Freytag's Arab. Prov., ii. 48: and see also EM, p. 228.])

قَدُوحٌ also signifies A well (رَكِىٌّ) of which the water is laded out with the hand: (S, K:) or a well (بِيءْرٌ) of which the water is not taken otherwise than by successive ladings [with the hand]. (A.)
