Protaetia cuprea

Protaetia cuprea, also known as the copper chafer, is a species of chafer in the family Scarabaeidae. This species is also known as the rose chafer and has a wide geographic distribution, extending from Canary Islands, Portugal, and Spain to the west towards Vladivostok in the Russian Far East, Mongolia, and North China. This species forages for pollen from flowers and fruits, such as apples, from trees. However, since fruit is scarce in the spring and winter, they only transition from a diet of pollen to a diet of fruits in the summer. Since pollen is richer in proteins and lipids than carbohydrates, while fruit is richer in carbohydrates, they are able to travel longer when on a fruit diet; this is due to their increased aerobic performance when fueled by high-carbohydrate content. This beetle is well-known for its flight ability, a skill that supports its foraging behavior. It has swift maneuvering ability and strong precision when landing on flowers and plants; it is able to do this due to the elasticity and mechanisms this beetle's wings possess.
