This is a close-up of an Atlas Moth. It was more complete specimen than the last Atlas Moth I posted ;)
I hope you like it!

Antennae (singular antenna) are paired appendages connected to the front-most segments of arthropods. In crustaceans, they are biramous and present on the first two segments of the head, with the smaller pair known as antennules. All other arthropod groups, except chelicerates and proturans which have none, have a single, uniramous pair of antennae.Antennae's also are used to send signals to communicate. 20% of all bugs have antennaes.

Antennae are jointed, at least at the base, and generally extend forward from the head. They are sensory organs, although the exact nature of what they sense and how they sense it is not the same in all groups, nor always clear. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially olfaction (smell) or gustation (taste).

In insects, olfactory receptors on the antennae bind to odour molecules, including pheromones. The neurons that possess these receptors signal this binding by sending action potentials down their axons to the antennal lobe in the brain. From there, neurons in the antennal lobes connect to mushroom bodies that identify the odour. The sum of the electrical potentials of the antenna to a given odor can be measured using an electroantenogram.

The three basic segments of the typical insect antenna are the scape (base), the pedicel (stem), and finally the flagellum, which often comprises many units known as flagellomeres. The scape is surrounded by a membranous region of the head. It pivots on a single marginal point called the antennifer, allowing it to move in any direction. The number of flagellomeres can vary greatly, and is often of diagnostic importance. True flagellomeres have a membranous articulation between them, but in many insects, especially the more primitive groups, the flagellum is entirely or partially composed of a flexible series of small annuli, which are not true flagellomeres. In many beetles and in the chalcidoid wasps, the apical flagellomeres form a club, and the collective term for the segments between the club and the antennal base is the funicle (or funiculus); for traditional reasons, in beetles it is the segments between the club and the scape, but in wasps, it is the segments between the club and the pedicel. In the groups with more uniform antennae (for example: Diplopoda), all segments are called antennomeres. Some groups have a simple or variously modified apical or subapical bristle called an arista (this may be especially well-developed in various Diptera).

Thanks for viewing :D

Hi Joey,
I cant believe 25 views so far and no one has commented on this super macro job you captured. This is an excellent close-up of this moth the details in the antennae are very sharp. Very nicely done. :)

Now that puppy jumps right off the page! And I just left Annick's soothing patterns and on to your almost frantic vibrations...quite the contrast but wakes the brainpan so early in the am. Nice work Joey and I say work, 'cus you should be getting paid for this:-)

Well done!

Hi Joe.
Yes. I really like it. Excellent macro shot. I welcome use macro converter. Its optic quality is perfect. And you have proved it. Terrific magnification ratio, sharpness and details. I am impressed with POV too. Bravo and kind regards.

Hi joe . Just a short quick note to say good shot, running late sorry.
Nick..

Hi Joe
Excellent picture. Your object looks like an alien. :)
Very good depth of field and good black background (it contrasts with the moth so it is even better visible).
Just one thing is worse - that is the fact that antenna from the left side is cut (but I can imagine how difficult was to take this picture).
Congratulations

Hi Joe,

Fantastic macro of this moth. He looks like he will fly right off the computer screen. Vivid colors and fine details. The wings are absolutely amazing!!!

It's a fantastic work of colours and lights,very very nice,thanks for share,Luciano

Great close up look at these amazing antennae Joe.
I'd say this one is definitely a moth as opposed to a butterfly.
No mistaking this onbe at all.
Awesome shot.
Cheers

Hi Joe

This is a very interesting photo with a most impressive subject - those huge antennae of the atlas moth.
The close-up level your reached here is impressive and the details you managed to get are great and very sharp. Also, the exposure and flahs are nicely controlled and balanced, giving you good lighting on your subject(s).
It's a pity you didn't use a bigger DOF to try and get the second one in full focus, too. But i can understand perfectly why...you can never be sure of these things by looking on the LCD from the camera, right? :)
Anyway, it's still a great macro.

Bravo and TFS

Hi Joe, this is amazing! so creative and works so well against the dark background. Details are so sharp and clear. Pov and perspective breath taking. An excellent shot all round.

Bonjour Joey,
Wooooooooow ! Superb close-up for this impressive moth, good details on antennas...
The "+++" : composition, subject, pose, POV, sharpness, DOF, warm colors, contrast with dark BG, light & exposure, useful complementary note...
The "-" : nothing...
Bravo and thanks for sharing,
Christian

Oh wow!!!!!
That is amazing!!!
Excellent macro and fascinating. Just fascinating!!!!
Perfect clarity, perfect sharpness, perfect perfect! :)

Hello Joe,
This is an excellent presentation of the 'feathered' antennae of a male Atlas Moth. The structure is well shown in sharp detail and the lighting and coloursa superb thanks to the good use of flash. The POV and composition are pleasing too.
Well done, TFS and enjoy the rest of this Sunday,
Ivan

Très impressionnat magnifiques détails et superbes couleurs, UNE TRÈS GRANDE RÉUSSITE.
