What family of plants are Cabbage White larvae notorious for feeding heavily upon?
Answer
Brassicaceae
The Cabbage White (*P. rapae*) is often categorized as a notorious garden pest due to the specialized feeding habits of its larvae. The caterpillars exhibit a strong preference for plants belonging to the mustard family, scientifically known as Brassicaceae. This family encompasses a wide range of both cultivated vegetables that gardeners prize, such as cabbage, broccoli, and kale, as well as various wild mustard species commonly found in uncultivated areas. This specific dietary requirement directly dictates where the butterflies are most likely to be found laying eggs, as the habitat must support the presence of these necessary food sources for the developing young.
