Winner, Nature's Pot-of-Gold side-by-side challenge, Yin & Yang 4-09
Blue Dasher dragonfly - spring 2017 - Morgan County, Alabama. There appears to be traces of a spider's web on its wings.
The Blue dasher (Pachydiplax longipennis) is a dragonfly of the skimmer family. It is common and widely distributed in the United States.
Mature males develop a bluish-white pruinescence on the back of the abdomen and, in western individuals, on the thorax. They display this pruinescence to other males as a threat while defending territories at the edge of the water.[2]

The Long Dash?
Many grass skippers are so similar that I find it is impossible to positively identify grass skippers in the field. I researched and unsuccessfully attempted to identify some of the skippers that I had photographed. I found that they fitted the description for several species including the long dash. As I like the name long dash I have decided to tentatively identify them as this species until others correct me.

I think this is a blue dasher, if I am wrong , someone please tell me.
Thanks to those whom confirmed the ID and let me know that it is a male.
NS 822 with a very long coal train with 5 engines and 250 coal car blast through Petersburg. This was a really nice train for me because i like catch the dash 9 on NS before there all AC44C6M, and had a ACe throwed in there to.

A companion macro of the male Blue Dasher, and the pair to start the rest of the dragon and damsel summer "series."
Very few macros are taken from behind the head of dragonflies. That's probably because the eyes are the most noticeable characteristic of dragons. The dragonfly uses 80+ percent of its teeny brain to see 360 degrees. Each eye has 30,000 cells which provides it with a mosaic of the world around it, but what the dragonfly is really tracking is movement and it is a successful hunter 95-97% of the time! It's no wonder this creature has been around for 330 million years! (Btw, 10 percent of the brain is used for flight. I assume that the other 90% is all about sex since that's what's left of its use of its short life span above water.
All that said - and it still truly fascinates me - there are few close up shots or macros that are of the back of the head or the muscles that control flight. The latter in this image are the segments behind the head and on top of the thorax. I suggest that you look up a You Tube video for "Dragonflies and Flight" or "Dragonflies and Hunting."
The same is true only on a slightly smaller scale for the only other member of the Odonata, the damselflies. They are the real gems and my goal is to get head-on closeups of damsels which are scary beautiful with the eyes better defined (there is a space between the eyes of damsels, and almost none with dragons).
The one question that I have left is ... what are the hairs for behind the eyes of the dragonfly? Well, nobody knows. Working in tandem with the three ocelli (smaller eyes) which are extremely sensitive to light intensity change, it is believed that their those hairs function are related with flight stability. But again, no one is quite sure. After all, when you're subject's brain is only a few cells, it's hard to communicate even with yes-no questions.
I also decided to try this macro because few images are of the odonates' wings from this point of view. Fortunately, the wings are so transparent in most species that you get rather good views of how four of the six legs are used for grasping and perching. The two smallest legs can be seen and are used mostly for brushing the eyes and cleaning the mandible after a meal. Considering the habitat of odonates, they are extremely neat insects, but so are flies if you want to carry this to extremes.
This is one of the rare shots that I have managed to get of Dash. True to his name, he barely sits still! He is only 18 months old and still very much a puppy :)
Alexandria Dash 300, a 2011 Gillig 40' hybrid, on route 30 at King St-Old Town Metro Station in Alexandria on Thursday, June 9th, 2022.
Female Blue Dasher. Female dragonflies generally hide, so they are more difficult to find and photograph, than the males who often perch and display prominently. This female blue dasher is very different than the more flamboyant blue males (see photo in the comment box) but those eyes are beautifully colored.

A collection of Dash 8's....
CN 2031 leads the south bound L532 freight over the WABIC Diamonds in Decatur, Illinois on a cloudy Saturday evening. Note the FRED hanging off the front of the 2031.
Locomotives: CN 2031, CN 2155, & GECX 7676.
- CN 2031 started life as CNW 8532, which later became UP 9054.
- CN 2155 started life as ATSF 840, which later became BNSF 840 and sold to the CN around 2010.
- GECX 7676 still wears the CSX YN2 paint scheme and original number, built in '91 for the CSX.

Fredry...
A rather unknown sport of sorts here is the commonly seen "racing for the tram". I do not excel in this "sport" and will probably not be given any medals anytime soon, but I do appreciate the fact that others are much better at it than I...

After arriving back into town, A700 pulls south of Junta to shove the train back into North Yard. The pair of Dash 3 EMDs sounded good with nearly 40 cars up the steep grade of the yard lead.
On the night of March 27, 1996 I had the scanner on and heard this guy requesting his meal enroute as he was coming through Rochelle, IL. By this time after the Union Pacific merger, the usual "beans at Dekalb" was denied. But on this evening, the dispatcher let him make the stop. Being a fan on the C&NW Dash 8's--and especially the only one that ended with the number '23', I made my way down to Dekalb to find them behind The Junction shopping plaza on the west side of town. A time exposure, coupled with a clear 25 bulb on the nose, produced this view of the C&NW 8523 and 8718 against the Northern Illinois night.
Female Blue Dasher. The bright blue males are much more commonly seen displaying at the edge of ponds as the females normally hide in the grass.

Facts:
DASH is 5 years old and in Kindergarten
DJ is a GIANT in 3rd grade wearing Mens small & size 8 men's shoes
THROW BACK THURSDAY
3 years ago
DJ was 5 years old (he was basically as small as DASH is now)
Dash was still using a binky
We lived in California
Does that mean Dash is going to be a GIANT too?!!!
...best viewed large.
Good morning and Happy Dragonfly Thursday. Today's featured dragonfly is the female Blue Dasher (Pachydiplax longipennis), along with the male of which I included a photo in the comment section with another female for comparison purposes.
The female (and immature males) are mostly brown in color, with a double row of yellowish lines down the dorsal surface of the abdomen. There are also yellowish markings down each side of the abdomen as viewed laterally. Eyes of the females are green to brown, and as with the males, the face is white.
I hope you enjoy this short series on this very common North American dragonfly and find the commentary in the comment section informative.
Thank you for stopping by...and I hope you have a truly great day.
