What is the difference of dung bettle and stag bettle?

Dung beetles and stag beetles differ primarily in their diet and appearance. Dung beetles primarily feed on animal feces, which they use for nutrition and as breeding material, while stag beetles are known for their distinctively large mandibles and primarily feed on decaying wood and plant matter. Additionally, stag beetles are often larger and have more pronounced sexual dimorphism, with males exhibiting larger jaws for combat over mates. In contrast, dung beetles are typically smaller and less ornate.
