I'm thrilled to report tonight that I collected the first monarch eggs of the season here in King of Prussia, PA (7 miles west of Philadelphia) in a vacant, overgrown lot that is for sale.


I checked about 20 plants and found 7 eggs. Only 1 of the 20 milkweed plants I checked had tiny holes, approx. the size made by a first instar caterpillar.



To date I have not seen a Monarch butterfly.
