Over the years I have developed the habit of checking milkweed plants carefully whenever I spot them. Milkweed plants host an extensive cast of colorful characters including ladybugs, milkweed beetles, and Monarch butterfly caterpillars (Danaus plexippus). Though I have been keeping an eye out for them for the last couple of months, I was unsuccessful in spotting a Monarch caterpillar until this past Sunday when I finally spotted one at Occoquan Bay National Wildlife Refuge.
This Monarch appears to be in one of its final phases of development as a caterpillar, when fattening up seems to be a priority before forming a chrysalis. It is not surprising, therefore, that most of the edges of the leaves in this photo have been gnawed on by the caterpillar. This caterpillar seems to be a little late calendar-wise in its path to becoming a butterfly, but I did spot several Monarchs yesterday, so it seems that the Monarch migration has not yet taken place, or at least not in its entirety.
