Larva purged excess fluids at noon on June 23, 2006 and was moved to  a  paper  tube device suitable for pupation then  placed in a dark  cupboard where  temperature was  about 75 to 80 degrees.  On June 26th, the pupa was removed from the paper tube and placed in an emergence container.

Other  host  plants (not photographed)

Other Information
P. machaon bairdi has one flight  in  the north of it's range and two in the southern part of it's range.  Since we are in the southern part of it's range,
it will not require being cooled for a few months to simulate a winter nor a simulated spring  before the pupa develops and  emerges  as an adult  this year.
