Here’s a little biology lesson for you: the primary difference between dragonflies and damselflies is how they hold their wings at rest. A dragonfly holds his wings perpendicular to his body, while a damselfly holds his wings parallel to his body. Lesson over. Here’s a photography lesson: prepare to be very frustrated while photographing damselflies because inevitably the autofocus in your camera won’t recognize them so you will have to switch to manual and about the time you get them into focus, they will fly away. Every time. Getting this shot isn’t a problem for a world-class wildlife photographer such as myself, but you might have these kinds of difficulties.
