Not exaclty sure.  As you just posted it a few days ago, I don't think you're too late. 


Just found this on Google which says the eggs are laid in late spring to early summer.  Also links to a control page...

EDIT:  I followed the link to the control page, and it is incredibly detailed and informative.  Definitely check it out...
