Please report this on Journeynorth.org as the 'first egg' map shows that they haven't progressed further than central New York and northern New Jersey.
Last year here in Salem, MAm, I found 24 eggs the last week of May. 12 made it to butterflies. THis year, so far, I have found no eggs, neither in my Waystation #2638, nor in any of my several "wild patches". I am getting very anxious if I am to top my numbers from last year, they had better arrive soon.
