Attached are 2 photos of the same Meadow Fritillary from July 12 - one taken on the mountain mint back in Fred's field, and one on the nearby Monarda.
I'm pretty sure it's a Meadow Fritillary - if I'm wrong, ask Patrick Carney. [Or Deedee! -- JW]
This is the first report I've seen of this species at the CF, but perhaps earlier records exist. I did not see it on the North American Butterfly Association list for the Celery Farm, here.
It has been seen at DeKorte Park -- on Butterfly Day three years ago.
Thanks, Julie, for the report and the photos!
