G'day,

Or the time in between such events large enough... for instance cicadas only
come out every 3, 5, 7, 13, 17 or 23 years (I don't think I've forgotten any
kinds, but there may well be more) and theoretical studies have confirmed that
such a behaviour in a predator would make it almost impossible for a prey item
with a lifespan of a few years to counter the pattern of emergence and food
use.

Now there's a scary thought.
