Butterfly #15 — Orange Sulpher

colias eurytheme

Moraine Hills State Park, Illinois

I was walking through an open weedy glade about halfway around the Leatherleaf Bog trail. The sulphur was flitting over the path and the grass along its edges. It landed frequently. When perched, its wings were tightly closed. Underneath, it was very similar to a Clouded Sulphur, but there was a trace of orange visible along the upper edge of the hindwing.

It flew around my legs, and I could easily see the orange patch and solid black border on the upperside of the forewing. It was about the size of a Cabbage White and Clouded Sulphur.
