Which of the following is not an example of an anobiid beetle?

The correct choice highlights that the red flour beetle is not classified as an anobiid beetle. Anobiid beetles belong to the family Anobiidae, which primarily includes pests that are known to infest wood and stored products. The red flour beetle is part of a different family, specifically Trogossitidae, and is more commonly associated with stored grain products rather than wood or structural damage.

In contrast, options such as the granary weevil and the confused flour beetle fall under the broader category of beetles that either directly damage grains or are found in association with stored products, while the common furniture beetle specifically targets wood, particularly in furniture and buildings, thus categorizing it within the anobiid family. Each of these beetles has distinct behaviors and habitats that define their classifications, underscoring why the red flour beetle does not fit in with the anobiid examples.
