cabbage root fly

A small fly (Delia radicum) whose larvae feed on the roots of cabbage and other brassica plants, causing significant damage to crops.
In agricultural and horticultural contexts, it refers to both the insect pest itself and the damage it causes. The term may also be used metaphorically to describe a persistent, hidden problem that undermines something from its foundation.
