Gray Comma (Polygonia
progne) Fermilab, Kane County, Illinois July 14, 2002 Gray Comma is a woodland
butterfly, found
at Fermilab in the "Big Woods" (ELM-24) on the western part of the
site.
They seem particularly fond of the semi-open Hawthorne grove at the
western
edge of the woods, where I have reliably found them every year for four
years now. Gray Comma does not seem to be a common butterfly in
the
Chicago area. The only other place I regularly find them is at
Waterfall
Glen Forest Preserve in DuPage County, another high-quality
woods. See Gray Comma metamorphosis for
some photos of a captive caterpillar, its chrysalis, and the emerged
adult. |
