Kidaichū

The Kidaichū (寄大蟲; lit meaning Parasitic Giant Insects) are a species of beetle-like insects that are bred and utilised by select members of the Aburame clan as part of their Parasitic Destruction Insect Technique. Though initially small in size, if provided with the incorrect amount of chakra, these insects immediately begin to devour the flesh of their host, causing them to undergo rapid growth to ultimately giant proportions. While this trait makes them effective at damaging enemies, as noted by Shino Aburame, it also makes these insects particularly troublesome to harbour even within the user's own body.
