Enerugī are creature that are based off of the Aburame Clan's Kikaichū, to collect chakra for Dr. Kairo's needs. Though he later continued to advance the creature by studying mosquitos, giving it the ability to take blood from organisms, with a sting that is almost unnoticeable. It has wings that allow it to travel long distances and there are many different versions and sizes to complete different tasks. After about 3 years Dr. Kairo developed a new version allowing it to record battles through a little camera it contains in eye area.
