syrinx

sulphur butterfly ...which I caught on the wing out in the greenbelt while hunting antelope horns milkweed plants behind my fence...and I found that the folks at BaMoNA don't have any pictures that reveal the inner wing display, just the outer, closed wings. So I had to identify it from the other pics I got from it. All in all, a walk well spent, tiptoeing through the deer scat.
