Re: BORERS AND WATER


Greetings.

So, suppose the borer can survive under water in the rhizome, but cannot
survive under water when emerges to  pupate, or alternatively, can survive in
pupation but not when it emerges from pupation. Irises which are grown in land
which is soggy or underwater in spring are often high and dry in the later
months. Maybe native populations that do not dry out will not support the
creature long, but in those areas where the water is not a constant after
early spring, we find the borer can complete the cycle? 

Just thinking out loud with Kay.
