Hello TN friends. This is my first post in a while. I took this photo of the Blue Dasher Dragonfly last August at a local botanical garden near my house. I was using the kit lens (Canon EFS 18-55mm) with my Canon Rebel. Focal length was 55mm and ISO was 400.

Blue Dasher (Pachydiplax longipennis)
Order: Odonata
Suborder: Anisoptera
Order Description: Dragonflies
Family: Libellulidae
Family Description: Dasher

Naiad- This is a relatively small naiad with a length of 3/4 to 7/8 inch (18 to 21 mm). It is brownish above and bright green underneath. There is a single, rear-facing spine on each side of abdominal segments eight and nine, with those on segment nine being noticeably longer. There are no hooks on the back, as some naiads have.
Adult- This dragonfly is small to medium in size, with a length of 1 3/8 to 1 13/16 inches (35 to 45 mm), and has a fairly broad abdomen. Females and immature males are greenish on the face and thorax, with a brownish black abdomen marked along the top with two parallel lines of pale yellow to yellowish green dashes. Mature males are greenish on the face and thorax but the abdomen is pruinose blue. The wings are mostly clear but may be clouded with brownish yellow at the bases, especially on the hindwings.

This species is found from southern British Columbia east to Ontario, extending south through the U.S. from southern California east to Florida. It also occurs in the Bahamas. In Idaho, it can be found throughout the state at lower elevations, usually below 3000 feet (914 meters).

This dragonfly can be found near lakes, ponds and slow streams at low elevations.

Adult Flight Season:
Late June to October

Naiad- Naiads feed on a wide variety of aquatic insects, such as mosquito larvae, other aquatic fly larvae, mayfly larvae, and freshwater shrimp. They will also eat small fish and tadpoles.
Adult- The dragonfly will eat almost any soft-bodied flying insect including mosquitoes, flies, butterflies, moths, mayflies, and flying ants or termites.

The naiads live in submerged vegetation. They do not actively pursue prey but wait for it to pass by, a strategy which affords them protection from other predators. The naiads of this species can tolerate water with low oxygen content. This is used by biologists in Florida who interpret their presence as a possible indicator of low water quality. Naiads emerge as adults at night. Adults generally fly from late June to October. Hunting occurs from perches on twigs and rocks. This is the only member of this genus.

After males and females mate, the female flies singly, without the male attached, to lay her eggs by dipping the tip of her abdomen in the water while hovering above its surface.

Hello Ken
This is a very good photo and the you display this dasher very well. I think you have a good composition with the leaf poking into the photo from the bottom and the dasher basically filling the rest of the picture. The focus is very sharp and I like the colors. With a little more depth of field you could have had the head in focus as well and in my opinion there is a little bit of noise in the lovely background, but that is maybe due to the Iso400. Very nice photo.

Hi Ken.
I am glad to see you again. And your start in 2007 is excellent. Very nice clear colours, amazing combination of blue, red-brown and green colour tones. Sharpness of the dragonfly is very good as well as the POV and composition of the picture. Your simple lens has demonstrated high class. My best wishes in 2007 and TFS.

Hi Ken,
Good image.
I like the compo and the neutral BG.
good colors overall.

Hello Ken,
A really sharp image of this dragonfly.
I like a lot focus and details you got on the insect, their amazing blue tones and the pattern and strucure of the wings.
Very good composition, standing on the tip of the leave.
Congratulations and thanks for share,

Excelente macro Ken con buena definición, a partir del apropiado foco y profundidad (tal vez F6.3 o incluso F8 hubiese sido beneficioso), agudeza e iluminación, que brinda además bellos colores.
Me gusta el punto de vista captado que permite ver buenos detalles de las alas del insecto, realzados por el muy bien logrado fondo difuso.
Buen disparo, gracias por compartirlo.
Un cordial saludo desde Buenos Aires... Ricardo

Excellent macro Ken with good definition, starting from the appropriate focus and depth (perhaps F6.3 or F8 even has been beneficial), sharpness and illumination that it also offers beautiful colors.
I like the captured point of view that allows to see good details of the wings of the insect, enhanced very well by the diffuse achieved bottom.
Good shot, thank you for sharing.
A cordial greeting from Buenos Aires... Ricardo

Hi Ken, this is a great composition. I think you should have focussed more on the head rather than the thorax. Everything else is fine, well done.

Bonjour Ken
Une très belle prise de cette libellule qui n'est pas facile à photographier (je m'y suis essayé en vain et je n'ai réussi qu'une seul fois.). Belle composition et superbe lre BG.
Merci et au revoir...JP

Fantastic DOF&POV.Nice composition.TFS!!

Very beautiful shot of this dragonfly. Nice pose and composition with good lights and great details.
If you use "save to web" or adjust better the quality when saving to jpg, you will get less compression and therefore less noise, specially in this kind of backgrounds with subtle colour gradients.
Best regards, Felipe.

Hello Ken,
I like those colors, details, pose of the insect and this beautiful brilliance on its wings. Exposure, POV and composition are very good with sharp details and this BG is just perfect. Nice one! Thanks,
