I'd just be taking a shot in the dark, nitro, but app. 2 years, tops< a fairly glorious beetle lifespan, if you ask me!>

Beetle lifespans vary widely by species, but most live as adults for only one season (spring-summer).
Some live longer. For instance I've read that calosoma scrutator, the fiery searcher/caterpillar hunter (which is a real beauty) can live as long as 4 years.
