Eastern Comma

The Eastern Comma is another butterfly with punctuation on its lower wing.  You may remember I recently posted about another such critter, the Question Mark.  Besides lower wing punctuation, the upper wing pattern of the two species differ slightly (Kaufman). 

Last week, Erika and I found this Eastern Comma on a bench along the Cannon Valley Bike Trail in Goodhue County.  The butterfly appeared to be sucking sweat left by overheated bikers.  This species does not usually visit flowers, instead preferring sap, rotting fruit, dung, salts and minerals (Wikipedia).   Eastern Commas are found across most of eastern North America.

  1. Just back from visiting northern NY, Eastern comma in my folks' yard which is managed for butterflies and hummingbirds. The resident comma took exception to the two monarchs visiting the milkweed and chased after them. I watched him/her do it several times in a particularly favored spot. Interesting behavior since they have completely different food preferences from what you have written about.
