Which of the following is NOT an entomophagous insect?

• A. Preying mantis
• B. Darkling beetles
• C. Spiders
• D. All of the above

Answer: (B)

The correct answer identifies darkling beetles as not being an entomophagous insect. Entomophagous insects are those that primarily feed on other insects. Predatory insects such as the praying mantis and spiders fall into this category, as they actively hunt and consume other insects. Darkling beetles, in contrast, are primarily detritivores or herbivores. They typically feed on decaying plant material, fungi, or agricultural products, rather than preying on live insects. This fundamental difference in diet classifies darkling beetles outside the group of entomophagous insects, making them the correct answer to the question. Understanding the dietary habits of these insects helps clarify their roles in the ecosystem, as it highlights the distinction between those that are predators of other insects and those that fulfill different ecological functions.
