There is a species of wasp that can turn itself into a "sleeping beauty" for up to five years. - Apparently.
The Tarantula Hawk Wasp (Pepsis sp.) is a species of wasp that has a unique ability to survive for extended periods of time in a state of dormancy. When threatened, the wasp's body becomes immobile and enters a state of suspended animation, often referred to as "diapause". This allows the wasp to survive harsh conditions such as extreme temperatures, lack of food, and even the hibernation of its host tarantula. Scientists have verified this behavior in laboratory settings.
