The above photo is a Fritillary, I believe, and I managed to get a shot of it coming in for a landing. Note the shadow it's casting on the ground. This one was landing on nearby Spreading Dogbane where it would alight one one flower after another continually for many minutes. I always watch as long as possible because there's a high probability that on one of these blossoms it will get nabbed by a Goldenrod Crab Spider.
Now we're back to the text I wrote for the original post:I didn't use a telephoto here, just a standard 55mm lens. Out by Gilson Creek, a mile past Oakland Camp, I practiced my quiet approach and got within a foot of this Damselfly. Later I got some nice close-ups of Swallowtail butterflies and Monarchs, including a caterpillar. Will post those later, along with flowers of the day.
