I went back to Yardley Chase in the hope of trying out some in-flight photos of Downy Emeralds. None were flying, so I tried to capture some of the many Four-spotted Chaser. Boy, are they fast!! I noticed that they hover around their territorial perch and following their behaviour, I managed these two photos. Both taken with Canon 40D and 55-250mm IS lens. I tried to photograph an oviposting female, but in all the photos I took, the camera focused on the background and not the female, so none came out well.
