Blue Dashers are one of the most abundant dragonflies in the U.S. and can be found near slow moving water sources, marshes and ponds. Adults have four wings with two noticeable dark streaks in them. Adult males have a chalky, blue color from head to abdomen that ends with a black tip. Their heads contain their large eyes which take on a metallic sheen in certain lighting. The female coloring differs from the male. Her abdomen is black with yellow stripes along the sides and top. Her wings do not contain the aforementioned streaks and their abdomens are stubbier. The thorax has yellowish-green striping not seen on adult males. Juvenile Blue Dashers are not blue yet. They have green and yellow stripes on the thorax and yellow dashes along the side of the abdomen, much like adult females.
Males are often seen around water's edge, protecting their territory from other males. They will flash their blue abdomens as a warning to each other. Females usually perch on vegetation and only approach the water when they are ready to mate. Both genders stick their abdomens upright in the air when perched, as if on alert, and they snap their wings closed after settling down. Like other dragonflies, the ecologically beneficial Blue Dasher contributes to pest control by consuming hundreds of smaller insects each day.

Dorsal view
I like to get both dorsal and ventral views if I can. I posted both views of this one.

A White Squirrel decides to take his dinner (walnut) up to the safety of a tree. This one has a dirty nose from rooting around on the ground to find this walnut.
This male was spotted and photographed by my wife Beatrice, while perched on a car antenna in the parking lot of McKee-Beshers Wildlife Management Area in Poolesville, Maryland.
Post-processing by me.
I'm behind - it's been a busy week! A bear, 2 storms, landscaping & yard clean-up. I'll be checking by ... hope everyone is good!
btw this female Blue dasher was a tiny thing - maybe an inch long

Male Blue Dasher sitting on some grass in the front yard, cropped a bit. Another in the Summer 2019 breakout year for being able to get a decent shot of a dragonfly! I have seen a few other varieties in the yard that I'll have to work on for my yard series.

Liverpool's famous Santa Dash saw thousands of runners make their way through the city centre dressed in red and blue Santa suits.
The Liverpool Santa Dash is the biggest and longest established Santa Run in the UK and in just its second year in 2005 it received a Guinness World Record status for the Biggest Santa Gathering. Thousands of runners took part in the charity fundraiser which started at the Pier Head (4th December 2022).
The runners then made their way around a 5k course through Liverpool city centre, ending at the Town Hall where race finishers were greeted by Christmas characters and fake snow.
This photo was taken about 200m from the finishing line, I think he was getting ready to capture it for himself.
The people in the background weren't finished, they had stopped part way to watch the Batala Band before finishing the rest of the course!

This is the place I saw the rare sinuous snaketail, BTW.
ZWSPLAC, one of the hottest Z trains on the BNSF system somehow got a H1 Dash 9 leader on this day. Here they are cruising through Mazon.
The Blue dasher (Pachydiplax longipennis) is a dragonfly of the skimmer family. It is the only species in the genus Pachydiplax. It is very common and widely distributed through North America and into the Bahamas.
Although the species name longipennis means "long wings", their wings are not substantially longer than those of related species. Females do, however, have a short abdomen that makes the wings appear longer in comparison. The blue dasher grows up to 1-1.5 inches long.
The males are easy to recognize with their vibrant blue color, yellow-striped thorax, and metallic green eyes. Females are somewhat less colorful than the male, an example of sexual dimorphism. While they have a matching yellow-striped thorax, their abdomen has a distinct brown and yellow striping that sets them apart from the male, along with contrasting red eyes. Both sexes develop a frosted color with age.
Built for the Cotton Belt in 1988 as SSW 8049, former Union Pacific B40-8 1848 is perhaps one of the "newest" locomotives preserved in a museum.
Donated to the IRM by the UP, the 1848 was doing its thing on the IRM's main line in 2014. Hopefully someday the Dash Eight will once again wear the scarlet and grey instead of what it wears now.

Blue Dasher, Pachydiplax longipennis, reflecting the morning sun at Seabourne Creek Nature Park, Rosenberg TX. Surprised he escaped the attack that broke his wing.

Don´t you like that great green color? It is like the renaissance of life, always struggling against time and weather...

Another look at a Blue Dasher from Mill Pond. She was quite cooperative and seemed as interested in me as I was in her.

Almost the exact opposite color of how it will look as an adult. My dragonfly ID book says blue dashers emerge right at the beginning of June in the Upper Midwest so maybe this was this beauty's very first morning. Photographed in the La Crosse River Marsh.
Caught this female blue dasher eating a meal, a fly or small bee possibly. Taken at Saul Lake Bog Nature Preserve near Rockford, MI

Dash 8s! Looking back 15 years ago today, there was quite a colorful set of power on CN's L506. This interesting duo was seen departing Northtown Yard, heading back to New Brighton, MN. CN 2108 had recently been repainted, and trailing was BCOL 4626, a C40-8M. Both of these units are now off of the CN roster. Time flies!
