The caddice larvæ are carnivorous; that is, they eat animal food.
The caddice larva makes its house of silk and sand and also lines it with a beautiful covering of fine silk.
You see it did not hurt the caddice larva to take away its house; it immediately went to work to build another.
You will be apt to find the caddice larvæ in any brook and in some ponds, and I hope you will always look for them.
Those lines that look as though some one had been ornamenting the bottom of the brook are made by our caddice larvæ.
You will always find these little brown-cloaked figures flitting about the brooks, where the caddice larvæ live.
Sometimes called "case fly," from the case or shell which the larva makes about itself; "caddice" is another way of saying "case."
"larva of the May-fly," 1650s, of unknown origin, perhaps a diminutive of some sense of cad.
