The first Monarch butterflies arrived in our field of milkweed in 2021 on the 6th of June. Not only were they early, there were three of them at the beginng. Soon more joined them and by the 18th we found our first egg in the field. There was a caterpillar on the 22nd of June.  Counts of Monachs seen in the field were done semi-regularly. and as of July 15, there were 21 Monarchs in the field.
