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.
Although the species name longipennis means "long wings", the 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.

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.
Dragonflies are, like most things, predator and prey. They are predators in their nymph stage, eating what they can capture in the water, and primarily insects as adults. Most of their life is spent in various nymph stages, lasting from months to years depending on the species. As the dragonflies that we see flying around, their life is short, up to five weeks for most species although I read that some species may live as adults for a few months and others for only a few days. I found this interesting from Wikipedia: 'There is also conflict between the males and females. Females may sometimes be harassed by males to the extent that it affects their normal activities including foraging and in some dimorphic species females have evolved multiple forms with some forms appearing deceptively like males. In some species females have evolved behavioral responses such as feigning death to escape the attention of males.' Males, can't live with them, can't live without them....
This one I believe is a Blue Dasher. (Pachydiplax longipennis)
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

The blue dasher is an insect of the skimmer family. It is very common and widely distributed through North America and into the Bahamas.These dragonflies, like others of their infraorder, are carnivorous, and are capable of eating hundreds of insects every day, including mosquito and mayfly larvae. The adult dragonfly will eat nearly any flying insect.

Just back from "the Swamp." Nothing, nada, nil, zero, zip. Soooo. one of my last Blue Dashers in 2019. I thought I might need it for a lull, but didn't figure the lull would be as early as the last two weeks in August in northern California. I must say he was a beauty, as fresh as if he had emerged in May or June, this species prime time in this part of the state.
If I ever wrote a book on photographing dragonflies, I would give each species a rating as to how cooperative they are in terms of photographing them. The blue dasher would receive one of the highest ratings. They like to sit on the same perch totally still and then "dash" out to catch their prey before returning to the same perch. Photographed along the pond in Chad Erickson Park, La Crosse, Wisconsin.

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.
C-GUKH, a De Havilland Canada DHC-8-402 Dash 8-400, landing on runway 33 at Downsview Airport in Toronto, Ontario.
Serial number 4633 was arriving as DHC4633 (De Havilland Canada) after performing its first flight. It was four hours and 35 minutes long.
This aircraft is expected to be the last Dash 8 produced at Downsview, where De Havilland has been operating for 92 years. No date has been set for a resumption of the type's production, nor has it been announced where that might take place.
Dash 8 production totaled 1,304 units.
They included 299 -100s, 105 -200s, 267 -300s and 633 -400s.
Eastern bluebirds must be migrating through as there were around 10 or so chasing each other around these dead tree snags.

CN C40-8 2033 leads ore loads South through Ramshaw, MN. The Iron Range Sub (and the Missabe Sub every now and then) is almost certainly the last place on a class one railroad were one can find three standard cab GEs together on a train,
