What specific plant family is utilized by *Pieris rapae* larvae as host plants?
Answer
Plants in the mustard family (Brassicaceae).
The larvae, or caterpillars, of the Cabbage White butterfly exhibit a strong specialization regarding their food source, tying directly into their classification placement relative to other insects. They are specifically noted for utilizing plants belonging to the Brassicaceae family, commonly referred to as the mustard family. This family includes globally cultivated agricultural crops such as cabbage, broccoli, and cauliflower. This reliance on Brassicas is a key factor in the species' pest status and its ability to thrive wherever human agriculture cultivates these specific vegetables.
