I ate dinner at Mallon Park before heading to Brookhaven College to do some black-lighting with the master naturalists.
This was the find of the day for us. John and Kendra Abbott and I were driving slowly along a forest road in the SE corner of Oklahoma in the Ouachita National Forest when we saw a large blue and black butterfly nectaring on some sunflowers a short way off the road. It was a huge butterfly and I thought at first it was a large female Tiger Swallowtail, but when we got the vehicle stopped we saw it was not a swallowtail and realized it was a female Diana Fritillary! We only had it in view a few moments before it took off back into the forest, but we obtained a few shots. I had seen a couple of males at a distance in Arkansas last year but was not able to take any shots, so this was the first time I've ever photographed the species. A very exciting record for us of this very local and often hard to find butterfly. I'll post 4 shots.
