Hi dear friends from TN.
As you can see in this picture Plumose Antennae have a feather-like shape.
I`d like that you check large version too, because then you can see more fine details.
Have a nice weekend!...and see you all on TN!

Antennae
Antennae function almost exclusively in sensory perception. Some of the information that can be detected by insect antennae includes: motion and orientation, odor, sound, humidity, and a variety of chemical cues. Antennae vary greatly among insects, but all follow a basic plan: segments 1 and 2 are termed the scape and pedicel, respectively. The remaining antennal segments (flagellomeres) are jointly called the flagellum.


Pheromone binding and inactivation by moth antennae
Richard G. Vogt & Lynn M. Riddiford
Department of Zoology, University of Washington, Seattle, Washington 98195, USA

The antennae of male silk moths are extremely sensitive to the female sex pheromone such that a male moth can find a female up to 4.5 km away1. This remarkable sensitivity is due to both the morphological and biochemical design of these antennae. Along the branches of the plumose antennae are the sensilla trichodea, each consisting of a hollow cuticular hair containing two unbranched dendrites bathed in a fluid, the receptor lymph2,3. The dendrites and receptor lymph are isolated from the haemolymph by a barrier of epidermal cells which secreted the cuticular hair4−6. Pheromone molecules are thought to diffuse down 100 Å-wide pore tubules through the cuticular wall and across the receptor lymph space to receptors located in the dendritic membrane6,7. To prevent the accumulation of residual stimulant and hence sensory adaptation, the pheromone molecules are subsequently inactivated in an apparent two-step process of rapid 'early inactivation' followed by much slower enzymatic degradation8,9. The biochemistry involved in this sequence of events is largely unknown. We report here the identification of three proteins which interact with the pheromone of the wild silk moth Antheraea polyphemus: a pheromone-binding protein and a pheromone-degrading esterase, both uniquely located in the pheromone-sensitive sensilla; and a second esterase common to all cuticular tissues except the sensilla.

Thanks for posting..

ciao Francisco!
excellent study the morphology of the antennae in this macro
amazing details of this "fishbones "

have a nice w.end sERGIO

Hello Francisco,
a superb macro shot of this moth taken from a frontal POV with impressive details of its antennae and eyes, the large version is simply fantastic, a first class picture.

Hello Francisco,
Stunning close-up shot of a moth's head part. We can see all ultra-stuctural details
The POV and composition are perfect.
TFS and G's,

Hi MF Francisco,

An incredible macro capture of a moth's head part from frontal POV with impeccable details, great DOF and delightful composition.
TFS and have a nice night and WE MF!
Cheers,

Bayram

What a marvellous macro of this set of impressive antennae, Francisco!
It looks even better in the LP format.
I too have 105mm lens, but I have never been able to do such a fine macro with it.
Well done and TFS.

Ótimo enquadramento, ângulo de tomada da foto, contraste e detalhamento principalmente da antena tipo espinha de peixe.
Até a próxima.

Hello Francisco,

A strong face to face portrait!
And of course the fine details in the antennas catch attention, interesting framing of this creature...
Sharp fine details, colours are well reproduced!

Greetings,
