To the left are four photographs of dragonflies that are hanging out around our backyard ponds. These photos are of two individuals — the first three are of a male, the next of a female.
I based the original identification of the first individual as swift long-wing skimmers (Pachydiplax longipennis) on photo 349 and page 375 of the National Audubon Society Field Guide to North American Insects and Spiders. Perusing the What's That Bug? web site under dragonflies, I found a similar insect with the name "blue dasher." Checking the scientific name, I found that "swift long-wing skimmer" and "blue dasher" were the same insect. Other dragonflies indicated the sexual dimorphism might make the individual in the last photograph a female. Checking with a site on dragonfly wing patterns and another site on dragonflies starting here and following the photographs, I concluded they were both mature members of the long-wing skimmer/ blue dasher variety, with the latter individual being female. I found the last two web sites using "blue dasher dragonfly" as the search term in Google (without the quote marks).
If you click on the photographs, you'll get an enlarged version of the image. Yes, I'm proud of these photos! Taking these photographs was difficult. I learned that the automatic focus would not lock reliably onto the dead twigs these insects predictably perched on. By turning off the autofocus and "bracketing" the photos with slight adjustments to the focus, I found I was able to get a number of photos of these dragonflies. About one photo in 5 is perfectly focused. By bracketing the focus, I found that I was usually able to get a better focus than my first guess.
Taking these photos required I stand at awkward angles. My back now hurts. I think I'm going to go take some Aleve and go get dinner. I hope you enjoy these photos as much as I did taking them.
