Who says beetles cannot be cute? Take a look at those guys:

These little fellows are beetles of the species Pachnoda marginata, commonly known as sun beetle or taxi cab beetle. Native from Africa, they reach up to 30 mm as adults and 60 mm as larvae and are one of the most common beetles raised as pets.

The sun beetle has nine subspecies, each with a particular color pattern. The most well known subspecies is Pachnoda marginata peregrina and is the one shown in the photos above.

Since the sun beetle is easy to keep in the lab, it has been eventually used in scientific studies, especially some related to the neurology of the olphactory receptors.
