[Note Guidelines] Photographer's Note
This insect, the small, boreal cicada Okanagana rimosa, was photographed during Kouchibouguac National Park's first ever full-fledged "Bio-Blitz" day, on July 16th, 2011.

It's identity was confirmed by Dr K.G.A. Hamilton of the Canadian National Collection of Insects and Gerry Bunker of "Massachusetts Cicadas".

Okanagana rimosa is much smaller than most North American Cicadas (30-40mm including wings)) and apparently sings earlier in the year and definitely has a much weaker song than our common species in the area, the Dog-Day Cicada (Tibicen canicularis). Notes from the site "Massachussetts Cicadas" had this to say about it:

"Okanagana rimosa is a small cicada. At roughly 3 to 4 centimeters long (including the wings) I liken it to about the same size as Magicicada cassini from the periodical cicadas. Their heads are narrower than the pronotum and is one of the keys to the classification of cicadas from this genus. Another key are the open (exposed) timbals in males. Eye color in live adults can range anywhere from dark grey to black."

Depending on who you talk to, we have either 3, 4 or 5 species of cicadas known for New Brunswick (Canada), two of which have been confirmed in the National Park, which is my workplace for about half the year.

With regards to the image, it is somewhat cropped. Also, in Photoshop CS2, I applied auto-contrast, then smart sharpen at 62% at 1.6 pixels, then about 5% saturation, then despeckle (all in that order), but I am not sure if this is the best treatment to get this image looking its best. I can repost the image totally unretouched at one point if someone would like to try their hand at fixing it in the workshop, as I would really like to know if I have a decent handle on how to fix images "properly".

Hi Denis,
Nice Cicada. A very colorful image, with a good Pov. I think that the DOF is really quite shallow. Interesting bug, I know I have never seen a Boreal Cicada posted here before. Well done.

Hello Denis,
A wonderful image of this colorful cicada. Excellent detail and just the right exposure. Love the intricate patterns in the translucent wings. I have never seen one this color before.

Bonjour Denis,
Beau sujet et belle présentation. En France, les cigales sont très difficiles à apercevoir mais on les entend facilement.
Belles couleurs et excellente netteté

Interesting Cicada species Denis! Beautiful photo too! Good composition, wonderful BG, fantastic colours and good sharpness.

Hello Denis,
Very nice photo of this Cicada in beautiful light and colours. Good sharpness and details. Pleasing contrasting background.
I hope to see a photo from you of a Saw-whet Owl, because of your name ;-)

Bonjour Denis,

Fine composition of this Boreal Cicada. I've heard them sing but this is a first time for actually viewing one. The colors are pure & the POV shows the distinctive features so well - especially the stained glass like wing. Very nice work!
