Les yeux compos\u00e9s et les ommatidies
<\/strong><\/em><\/u><\/span>La vision des odonates est complexe, comme pour tous les insectes aux yeux compos\u00e9s.
Quand on clique sur la photo ci-dessus, on voit correctement les ommatidies\u202f; ce sont les unit\u00e9s \u00e9l\u00e9mentaires, qui composent l\u2019\u0153il de la libellule. On en compte jusqu’\u00e0 30.000 chez les Aeshnidae (Anax junius a exactement 28,672 ommatidies dans chaque \u0153il \u00e0 maturit\u00e9\u202f; Land and Nilsson 2002) ce qui constitue le record pour le monde des insectes(1). Leurs yeux, les plus gros de tous les insectes, leur permettent de voir pratiquement dans toutes les directions… sauf directement en arri\u00e8re.
Ces ommatidies ressemblent \u00e0 toutes celles pr\u00e9sentes chez les insectes et forment une structure conique \u00e0 section hexagonale, la partie la plus large du c\u00f4ne est \u00e0 la surface de l\u2019\u0153il recouverte d’une lentille (corn\u00e9e, cristallin…), la partie la plus \u00e9troite, profonde, est une structure photosensible appel\u00e9e rhabdome dont s’\u00e9chappe un axone qui relay\u00e9 par un ganglion atteint le cerveau.
L’image r\u00e9sultante peut se comparer \u00e0 un pixel et l’image globale est recompos\u00e9e au niveau du cerveau environ 200 fois par seconde\u202f; en cons\u00e9quence, si vous invitez une libellule au cin\u00e9ma, choisissez un film tourn\u00e9 en 200 images secondes, sinon notre standard humain (24 ou 30 I\/s) lui para\u00eetra d’un autre \u00e2ge, compl\u00e8tement saccad\u00e9… \ud83d\ude42<\/p>\n\n\n\n

Les yeux des odonates ne sont pas mobiles comme les n\u00f4tres, mais leur conformation leur permet de voir presque \u00ab\u00a0partout \u00e0 la fois\u00a0\u00bb sans bouger la t\u00eate, et sans doute ult\u00e9rieurement de \u00ab\u00a0se concentrer\u00a0\u00bb sur l’image qui n\u00e9cessite le traitement le plus urgent.<\/p>\n\n\n\n

\n\n\n\n

Les pseudo-pupilles<\/strong><\/span><\/span>
Cette formation d\u2019ommatidies accol\u00e9es est responsable d\u2019un ph\u00e9nom\u00e8ne de pseudo-pupilles visible chez tous les insectes, mais plus facilement observable pour les odonates en raison de la grande taille de leurs yeux et de la couleur parfois claire de ceux-ci. Leurs yeux semblent montrer des pupilles sombres, parfois multiples qui donnent l\u2019impression de suivre le d\u00e9placement de l\u2019observateur.<\/p>\n\n\n\n

Quand le regard de l’observateur tombe dans l’axe d’une ommatidie (ou de plusieurs tr\u00e8s voisines) il per\u00e7oit un point noir d\u00fb au fait, que dans cet axe, la lumi\u00e8re n’est pas r\u00e9fl\u00e9chie par les cellules pigment\u00e9es qui la tapisse mais \u00ab\u00a0absorb\u00e9e\u00a0\u00bb par la zone photo sensible profonde. Mais il ne s’agit en aucun cas d’une v\u00e9ritable pupille au sens du diaphragme de l\u2019\u0153il des mammif\u00e8res.<\/p>\n\n\n\n

\n\n\n\n

Vision des couleurs<\/strong><\/u><\/span>
On a longtemps dout\u00e9 que les odonates aient une vision en couleur, mais ils laissent tr\u00e8s loin derri\u00e8re notre vision trichromatique bas\u00e9e sur l’expression de 3 g\u00e8nes codant 3 opsines (prot\u00e9ines r\u00e9agissant \u00e0 l’\u00e9nergie lumineuse) ; les odonates en poss\u00e8dent de 15 \u00e0 33, 20 par exemple pour le Sympetrum frequens, dont 16 opsines destin\u00e9es \u00e0 la perception des couleurs. Ces opsines sont sp\u00e9cifiquement sensibles, chacune, a une certaine fourchette de longueurs d’ondes, certaines sensibles aux ondes courtes (SW), d’autres aux ondes longues (LW).
Anax parthenope fait partie des champions puisqu’il compte 33 g\u00e8nes pour coder les opsines dont 8 pour les courtes longueurs d’ondes et 21 pour les longues, et bien s\u00fbr tous les odonates \u00ab\u00a0voient\u00a0\u00bb les UV et le plan de polarisation de la lumi\u00e8re, ce dernier \u00e9l\u00e9ment joue certainement une part importante dans le contr\u00f4le du vol (2).
Les odonates voient donc parfaitement les couleurs, bien mieux que nous, et ils poss\u00e8dent des r\u00e9cepteurs sp\u00e9cialis\u00e9s pour les analyser tr\u00e8s finement.<\/p>\n\n\n\n

\n\n\n\n

Sp\u00e9cialisation r\u00e9gionale des yeux<\/strong><\/u><\/span>
Comme on le voit tr\u00e8s bien sur la photo ci-dessous (en cliquant …) les ommatidies ne sont pas de la m\u00eame taille sur toute la surface de l\u2019\u0153il. Elles sont plus larges sur la partie sup\u00e9rieure de l\u2019\u0153il, \u00e0 peine discernables sur la partie inf\u00e9rieure. Cette distinction morphologique correspond \u00e9videmment \u00e0 une diff\u00e9renciation fonctionnelle.<\/p>\n\n\n\n

\"Onychogomphus<\/a>
Onychogomphus forcipatus femelle, Chalonnes sur Loire (France – 49), 16\/06\/2017<\/figcaption><\/figure>\n\n\n\n

Les larges ommatidies permettent le passage d’un grand nombre de photons et la r\u00e9duction de la diffraction \u00e0 travers une lentille plus large a pour cons\u00e9quence une image plus nette.
Cette r\u00e9partition r\u00e9gionale des ommatidies s’accompagne d’une r\u00e9partition sp\u00e9cifique, quantitative et qualitative des opsines entre la partie haute et basse de l\u2019\u0153il. Ainsi, pour les anisopt\u00e8res, on note une forte expression des g\u00e8nes codant les opsines pour les ondes courtes (SW) et tr\u00e8s peu pour les ondes longues (LW) dans la partie sup\u00e9rieure de l\u2019\u0153il. L’inverse est vrai pour la partie inf\u00e9rieure.

On peut, comme l’ont fait les auteurs du document (2) trouver une justification \u00e9cologique et comportementale \u00e0 cette r\u00e9partition\u202f; la lumi\u00e8re solaire venant d’en haut est de forte intensit\u00e9 et biais\u00e9e vers les longues ondes, la lumi\u00e8re de l’environnement, venant d’en bas, r\u00e9fl\u00e9chie, tend \u00e0 \u00eatre de plus faible intensit\u00e9 et d\u00e9port\u00e9e vers les longues ondes.
Cela correspond parfaitement aux conditions rencontr\u00e9es par un anisopt\u00e8re perch\u00e9 sur le bord d’un \u00e9tang qui surveille son petit territoire en explorant et surveillant vers l’avant et le bas, d’o\u00f9 provient la lumi\u00e8re r\u00e9fl\u00e9chie, et scrutant (en m\u00eame temps\u202f!) le ciel pour y d\u00e9celer d’\u00e9ventuelles proies (ou pr\u00e9dateurs).<\/p>\n\n\n\n

Enfin, il a \u00e9t\u00e9 montr\u00e9 (3) que le bord sup\u00e9rieur de l\u2019\u0153il comportait une r\u00e9gion sp\u00e9cialis\u00e9e dans le traitement de la lumi\u00e8re polaris\u00e9e et cette zone intervient certainement dans le contr\u00f4le de la navigation de l’insecte.<\/p>\n\n\n\n
