جَرَادٌ
1.
[a coll. gen. n., (tropical:) Locusts; the locust; a kind of insect] well known: (S, Msb, K:) so called from stripping the ground, (A, Msb,) i. e., eating what is upon it: (Msb:) n. un. with جراد: (S, Msb:) applied alike to the male and the female: (S, Msb, K:) جرادة is not the masculine of بَقَرٌ, but is a [coll.] gen. n.; these two words being like بَقَرٌ and بَقَرَةٌ, andتَمْرٌ and تَمْرَةٌ, and حَمَامٌ and حَمَامَةٌ, &c.: it is therefore necessary that the masculine should be [in my copies of the S, “should not be,” but this is corrected in the margin of one of those copies,] of the same form as the feminine, lest it should be confounded with the plural [or rather the collective form]: (S:) but some say that جراد is the masculine; and جرادة, the feminine; and the saying رَأَيَتُ جَرَادًا عَلَى جَرَادَةٍ [as meaning I saw a male locust upon a female locust], like رَأَيْتُ نَعَامًا عَلَى نَعَامَةٍ, is cited: (TA:) it is first called سِرْوَةٌ; then, دَبًى; then, غَوْغَاءُ; then,
خَيْفَانٌ; then, كُِتْفَانٌ; and then, جراد: (A 'Obeyd, TA:) As says that when the males become yellow and the females become black, they cease to have any name but جراد. (AHn, TA.) [Hence,] اِبْنُ
الجَرَادِ, (T in article بنى) or ابن الجَرَادَةِ (TA in that article,) (assumed tropical:) The egg of the locust. (T and TA ubi suprà.)
