Which two beetles are known for infesting stored food?

The Drugstore beetle and the Cigarette beetle are indeed known for infesting stored food. The Drugstore beetle primarily targets a variety of dried goods, including grains, spices, and medicine, while the Cigarette beetle is often found in stored tobacco, but it can also infest other pantry items like dried fruits and nuts. Their ability to thrive in stored food environments makes them significant pests in homes, warehouses, and food storage facilities.

In contrast, while Rice and Flour beetles might potentially refer to pests associated with specific types of grains, the primary identifiers for these insects in stored food contexts are the Drugstore and Cigarette beetles. Ground and Carpet beetles typically target animal products and do not specifically infest stored foods, and Beet Leaf and Cucumber beetles are more associated with agricultural and garden environments than with stored food products.
