We have yet to have any Monarchs on our milkweed in North Ga, but I know someone in Memphis, Tn who has several on some milkweed I gave her. I saw my first Monarch of the year while on a walk today in Colorado right at the base of the foothills to the Rockies. I also saw quite a bit of common milkweed growing in the field.
We do have a Gulf Frifilary caterpillar on our passion flower vine and that has been our only butterfly caterpillar all summer.
