Stink Bug and its Spiracles
Feb 13, 2020 10:28:05 #
This is one of my preserved Brown Marmorated Stink Bugs. They are overly abundant, considered to be a pest and they make great subjects for the camera.
The first image is that of the stink bug positioned to show its lovely face.
The second image showcases the spiracles that are part of the breathing mechanism of insects. Spiracles are protected by hairs and valves with flaps, and are surrounded by spines, folds and ridges. They are controlled by muscles that open them when oxygen is needed. Then they close partially while insects rest. Spiracle size can also be adjusted in insects that live in dry climates, to prevent losing moisture. Each spiracle leads to a trachea and a sack like lung organ.
The third image provides a reference for the size of the stink bug to that of a dime.
The forth image shows how the stink bug is staged before the lens of the camera and the amount of working distance there is between the camera lens and the subject. It also illustrates how the lighting is diffused for these sessions.
The final image shows the how the camera rig is arranged, the accessories that I use and the lighting source.
As always, thanks in advance to all who view and for your comments, suggestions, questions and critique.

Excellent. And that is one productive rig you got there.
Thanks, Mark. I still struggle a bit with getting the subject into position. I reminds me of target shooting where when looking through a high-power scope where the slightest movement goes yards off the target.
I spend as much time turning, rasing, lowering, spinning the subject as I do everything else involved. I'm seriously looking at an X/Y and rotating axis positioner https://www.wemacro.com/?product=xyr-stage-with-specimen-holder. I have solutions for the Z axis so perhaps this will be a big help in my missing gear.
I also received a message that my 80mm f/2.8 macro 1X to 5X lens left Hong Kong today and is in route to the U.S. now so I expect that it will arrive sometime later next week. My hopes are that it will be comparable to the world-class Canon MP-E65 in a Nikon format.

I have run out of superlatives. I am excited to see how you get on with that new lens.
