I added the exclamation point in the title to fill a gap left by our punctuational butterflies. Eastern commas are usually fairly common at Mayslake Forest Preserve.
The week before, I thought that one of the comma’s less frequent relatives appeared.
Later I had to conclude that this was a question mark wannabe, a comma with a disruption in its namesake line. This was made clear by the upper wing pattern.
There have been appearances by two different moths in the same genus, and no ambiguity in this case.
These are tiger moths that commonly emerge this time of year, and I continue to see individuals of both species at Mayslake. The haploa caterpillars generally feed on a wide variety of plants, but I have no information on their local diet range.
Another common moth is the large lace border, one of the geometrid or inchworm moths.
Again, the relative abundance of this species probably is tied to its broad dietary range, which includes plants in several families.
