I tried to capture those tiny primitive insects running in the sun, on a rock covered by lichen, but when I approached my lens, they escaped very quickly. Finally, I captured this one. I saw after that it was moulting, that is why it didn’t escape.

Family: Machilidae
Order: Archaeognatha (jumping bristletails).
Subclass: Apterygota

Machilidae is a family of primitive insects. Along with the Meinertellidae, (only 2 families in of Archaeognatha order), they are among the least evolutionarily changed insects, appearing in the Devonian period along with the arachnids.
They are quite similar to the Thysanura, or silverfish, with which they are often grouped. They differ from the Thysanura in their form of locomotion, which relies more on jumping (up to 10 cm). This is acheived by flexing the abdominal segments and releasing them like a spring.
There are around 250 described species worldwide. These insects are wingless, elongated and more or less cylindrical with a distinctive humped thorax and covered with tiny, close-fitting scales. The colour is usually grey or brown, sometimes intricately patterned. There are three "tails" at the rear of the abdomen: two cerci and a long central epiproct. They have large compound eyes, often meeting at a central point.
Machilids undergo virtually no metamorphosis during their life cycle and both nymphs and adults are generally inconspicuous herbivores and scavengers, many species being restricted to rocky shorelines, but some found in well vegetated habitats inland. They can move very fast and often escape by jumping considerable distances when disturbed.

Hola Catherine

Vaya que insecto más extraño, no lo conozco, buena nitidez y contrastes con ese fondo de dos formas, bella composición y un buen POV.

Un saludo de Antonio

Haha:) what a big coincidence dear that we are neighbour tonight!
This is a perfect presentation of a Turkish jumping bristletail taken from a great POV with impecable details in its natural environment. The texture of the rock is also wonderful. Great work as usual Cathy!
TFS and have a nice night!
Cheers,

Bayram

Hello Catherine, wonderful shot of this creature from dorsal POV.
TFS and regards,
Bahadır

As I remember they are so small and rapid.
Very good capture with good details.
TFS.

Chère Catherine!

Je vois que tu as beaucoup de travail pour photographier cet insecte. Mais ta persévérence a bien été récompensée. Tu as saisi un moment intéressant qui montre l'insecte en pleine mutation. C'est rare de voir cela! Comme petite anecdote: moi qui aime aussi le côté abstrait dans la photographie de la nature, je suis intrigué par la belle structure dans le rocher que j'aurais exploré...

Amitiés

Markus

Hello Catherine,

very nice close up and composition from the insect and dry ground, it look a puzzle.

Good of sharpness and details.
Fine colours.

Good morning Catherine,
A very fine macro of this Springtail changing its skin. The dorsal POV shows its features with superb clarity and natural colours abnd the cracked clay BG add attraction to the image.
Thanks for this excellent contribution to TN.
Kind regards,
Ivan

Hi dear Cathy,
nicely taken image of a "primitive insect' with a complicated structure! Good day! In my opinion the image shows us quite well the anatomy of the creature. The colors are natural and the contrast pleasant. Those interesting cracks on the background are adding flavour to the image. Good composition and valuable notices.
Love and peace !
Cheers

Merhaba Catherine,
Gümüşbalığına (silver fish) çok benzeyen bir apteriygot türü. Eline sağlık, Türk dostu sevgili Catherine!
Selamlar,
Ömer.

Hi Catherine

Mes compliments pour cette photo,très jolie le point d'observation et aussi la qualité.
Bravo et au revoir...JP

Hi Carherine,

A very interesting species. You've never seen before.
Sharpnes, point of view and with the timing of the shooting has been very successful.
Species related to the successful introduction and operation.
Thank you for sharing.

Best Regards,
Mehmet

Hi Catherine. Great macro capture of this primitive insect.
The pov, dof and composition are fine.
TFS. Kind regards,

Bonjour Catherine,
Voilà une petite bête bien intéressante...une créature qui nous vient du fin fond des âges avec son allure et sa forme très archaïques. J'aime beaucoup aussi la palette de teintes grises.
Intéressant!
Bonne fin de semaine
Anne

Hy Catherine
I missed this one. In fact I did not have time to react when you post it. There are not many images here with primitive insects and are also part of our natural world. In fcat, are very interesting species, but not always in the direction of our camera's. Ok, are also very small and we are not walking in the knees to find them on the ground.
Very good sharpness as ussualy.
TFS and have a great week-end!
Oana

An amazing insect here and i guess it would be a hard subject to show beautifully as for me. But you achieved successfully, a great contribution to tn. i couldn't leave without mention the wonderful bg especially on the right side of the frame with those shapes and the texture what i feel in the frame. In my opinion it also dominates the "primitive insect" title.
Wow, these captures are from Turkey ha! i should have searched my country more attentively!
Congratulations,
Ersin

Bonjour Catherine,
L'insecte photographié appartient à la famille Meinertellidae. On peut distinguer cette famille des Machilidae par l'absence d'écailles sur le premier segment de l'antenne (sur la photo, c'est la partie basale de l'antenne avant le coude).
C'est une famille surtout présente dans l'hémisphère Sud, mais elle est représenté en Europe par 2 genres, Machilinus et Machiloides. Le premier se distingue par l'absence de "stylet" à la base des pattes 2 et 3. C'est le cas ici, mais on pourrait objecter que cela se verrait mieux sur une vue de profil. Cependant, j'ai la silhouette du Machilinus "dans l’œil" et je peux dire que c'est bien lui !
Le genre Machilinus a une très vaste répartition mondiale. Il est représenté "chez nous" par plusieurs espèces dans l'ouest méditerranéen, plus une espèce présente de l'Italie à la Roumanie, plus enfin et surtout par une espèce présente sur tout le pourtour méditerranéen. Cette dernière, Machilinus rupestris est la seule présente en France, et la seule que je connais bien. Celle de ta photo est visuellement identique. Je crois que c'est elle. Et c'est sans doute la seule espèce de Machilinus connue en Turquie.
