Dung beetles, also known as dung beetles, are insects that feed primarily on animal waste. They play an important role in the ecosystem, not only helping to break down organic matter and promote soil fertility, but also controlling parasite populations. Dung beetles come in many numbers and varieties, in many different forms, and some species are even extremely colorful and textured.

As a common insect, dung beetles are extremely adaptable in nature. Whether it's a dry desert or a wet forest, they find the right environment to live in. Dung beetles are best known for what they do: rolling dung balls. When they find animal feces, they quickly transfer it, using their forelimbs to roll the feces into balls for storage and consumption. This behavior is not only a way for dung beetles to forage, but also one of their reproductive strategies, with female dung beetles often laying eggs in balls of dung to provide rich food for their larvae.

The physiological structure of dung beetles is also very unique, the hind legs are strong and developed, suitable for rolling dung balls. Their forewings evolved into stiff covering wings that protected their soft hind wings. When dung beetles are threatened by the outside world, they are able to quickly hide in their surroundings, disguising themselves as part of the soil to avoid detection by predators.

The collection and preservation of dung beetles are key steps in the preparation of specimens. To obtain the ideal specimen, researchers usually select mature, healthy individuals. By fixing, drying and coloring, the morphological characteristics of dung beetles are preserved for further study and display. The completed dung beetle specimens not only show their biological diversity in morphology, but also provide important data basis for entomological research.
