If you visit to photograph the elk herds, you will definitely want to have a secondary target in mind. Summer heat is back and the elk will be gone by 8 or 9AM. My favorite second subject at this time of year are butterflies. Early rains have created strong summer wildflower blooms. For some reason hummingbird moths are thick this year in many places.
Below is my favorite hummingbird moth picture so far. I call it "pollen puss". My standard strategy for this sort of photo is to pick a flower composition I like and just wait, often for hours. I would say this photo took me 6 hours to get. As always, there is plenty of luck in getting a decent photo. I chose a top lit flower in this case for an out of the ordinary compo.
