▪ I. frass|fræs|
[a. Ger. frasz, f. root of fressen (= fret) to devour.]
The excrement of larvæ; also, the refuse left behind by boring insects.
1854H. T. Stainton Entomol. Comp. (ed. 2), The half-eaten leaves attest but too surely that some devourer is near. These indications of the presence of a larva are expressed in the German language by the single word ‘frass’, and we may, without impropriety, use the same word for the purpose of expressing the immediate effect of the larva's jaws, and the more indirect effect of the excrementitious matter ejected by the larva. 1860E. Adams in Trans. Philol. Soc. 91, Frass, the rejectamenta found at the entrance of the burrows of wood-boring insects. 18..Board of Agric. Leaflet No. 30. 1 If such apples are split in halves a passage can be seen leading to the ovaries or pip-centres, around which there is usually a mass of ‘frass’.
