No eggs so far this year
We live is a western suburb of Chicago and have been raising Monarchs for about 5 years. We haven't seen a single monarch yet this year and despite having over 25 milkweed plants we don't have a single egg yet. Last year by this date we already had over thirty monarchs hatch.
Any reason we haven't see any yet other than the cold wet weather?
I live in Minnesota and although I saw my first monarch the end of May (same as last year) I haven't had any eggs on my milkweed. After that first monarch, I have not seen any other monarchs in my back yard. It has also been a very cold, wet spring for us here so maybe this does have something to do with fewer monarchs. I have a lot of black swallowtail caterpillars right now, though.
