Only the larval stage of which group causes damage in stored products?

Explanation:
Stored-product damage is driven by what the larvae are doing inside the food. In moths, the caterpillar stage actively feeds on grains, flour, and dried goods, tunneling and contaminating the product. The adult moths, on the other hand, do not feed on stored foods, so they don’t cause the damage themselves. That makes moths the group where the larval stage is the damaging phase. (In other groups, adults may also feed on stored products, so the damage isn’t limited to the larval stage.)
