Eucaliptus snout beetle.

This is a closer detail of this curculionid I already posted HERE and HERE.

So this time I looked for some info about the antennae of the insects.

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 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).

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 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).

I found this info HERE.

Lovely clear picture of a snout beetle. One can just about count the bristles on his back and legs. Good DOF to bring out the important points. Great work, Felipe.
Regards,
Irmgard

Hi Filipe

Another fantastic macro shot from you, my friend!
The close-up level here is indeed magnificent and the details and textures you managed to pull off here are most impressive!
The eyes, the snout and the antennae are indeed great and well isolated from everything else in their BG (even if that includes some other parts of the beetle).
The colors are lovely and the lighting is also excellent!

Bravo and TFS
Horia

Hi Felipe,
Great study on antenna. My first time to observe antenna this close. A perfect picture. With all best wishes,
JC

Hi Felipe,
this is amazing - so close, so sharp, excellent work, I love it.
Thanks and greetings

Hi

Amazing detail here - colours also very good. Overall a very strong composition - of something I would not normally even notice!

Hello Felipe,
I can't say that I "love" this guy, but the details are truly amazing. Fantastic macro with fantastic focus and exposure.
An interesting encounter with this insect!
TFS. : )

Dear Cristina and Felipe,
you made a real personality out of this innocuous brown job! Good portrait with all the fine details, scales, pimples. Handheld? I suppose you support your arm. Is your antishaking device working in macro mode? Thanks for presenting the shot here.
My best regards to you both,
Dietrich

Hola Felipe y Cristina,
Extraordinario el aumento, nitidez, detalle y texturas conseguidas. Saludos
José Ramón

Muy buenas Felipe
Menudo macrazo del gorgojo que sacaste, es todo antenas.
Si me permites mi opinión, creo que con un difusor de luz para iluminar el otro ojo hubiera quedado de lujazo total.
En cuanto al resto esta fenomenal.
Un saludo

Hi Felipe,

Amazing MACRO shot
These details are SUPERB
Perfect compo, colours, POV and DOF

TFS Thijs

Hello Felipe and Cristina!
Very interesting POV showing in perfect way the antennae of this curculionid beetle. I like details and colouration, moreover DOF is so good that every single part of antennae can be easy seen! :)
TFS and best greetings from Lodz,
Radomir

A truly magnificent close-up macro of a Eucaliptus Snout Beetle's head and antennae, Felipe.
Each detail on the antennae in particular is crystal clear. The power of macro photography in its best manifestation, indeed.
Your note on the antennae makes an interesting reading.
TFS.

Un gran acercamiento. Estoy impresionado por la calidad. Un saludo.

José Luis.
