What is an "oil beetle"?

An oil beetle is a type of beetle characterized by its elongated body and oil-like secretions that it releases when threatened. It is commonly found in grasslands and meadows, and its bright colors serve as a warning to predators. The oil beetle has a unique life cycle, with the larvae relying on solitary bees for development. While the oil beetle is harmless to humans, it plays an important role in pollination and the ecosystem as a whole.
