To a geographical distribution of the widest extent, Diptera add a range of habits of the most diversified nature; they are both animal and vegetable feeders, an enormous number of species acting, especially in the larval state, as scavengers in consuming putrescent or decomposing matter of both kinds.
Occasionally a deer would wander under the shelter and eat some of it, but the J-shaped feeders protected most of it.
Carmen poured grain into the feeders and the smell of oats and honey brought a tidal wave of goats into the barn.
The vegetable-feeders attack leaves, herbaceous or woody stems and roots; frequently different parts of a plant are attacked in the two active stages of the life-history; the cockchafers, for example, eating leaves, and their grubs gnawing roots.
They are vegetable feeders, both in the perfect and larval stages, and are often highly injurious.
