La lumi\u00e8re frappait le carrelage avec une telle force, comme si elle fendait l’air, qu’\u00e0 cet instant pr\u00e9cis, une fine ligne argent\u00e9e a fil\u00e9 le long de la plinthe. Son mouvement \u00e9tait d’une pr\u00e9cision si silencieuse que la pi\u00e8ce semblait respirer \u00e0 son rythme. Je me suis accroupi, essayant de saisir le mouvement, et j’ai senti l’odeur humide du carrelage apr\u00e8s la douche. C’\u00e9tait un l\u00e9pisme argent\u00e9, un voisin nocturne que la plupart des gens ne reconnaissent qu’\u00e0 son bruissement soudain.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

C’est amusant : avant, j’aurais pens\u00e9 que c’\u00e9tait un cafard mutant ou un arachnide exotique. Mais des ann\u00e9es d’\u00e9tudes m’ont prouv\u00e9 le contraire. Plus j’observais cette minuscule cr\u00e9ature, plus je comprenais qu’il ne s’agissait pas d’un monstre pr\u00e9historique de l’\u00e8re des dinosaures, comme le pr\u00e9tendent certaines sources douteuses. Sa famille est apparue bien plus tard, il y a seulement une centaine de millions d’ann\u00e9es. Une conception primitive, mais \u00e9tonnamment rationnelle, de la nature.<\/p>\n\n\n\n

Une autre chose a attir\u00e9 mon attention : pourquoi s’installent-ils si facilement l\u00e0 o\u00f9 nous vivons ? La r\u00e9ponse \u00e9tait presque audacieuse. Il leur faut un taux d’humidit\u00e9 proche des tropiques et une temp\u00e9rature confortable pour marcher pieds nus. Ils se nourrissent de tout le reste. Colle, amidon, papier, fragments de chitine\u2026 Il semble que cette petite trace m\u00e9tallique sur le sol puisse transformer en nourriture tout ce qui contient des glucides.<\/p>\n\n\n\n

J’ai pass\u00e9 mon doigt sur le carrelage sans le toucher, comme pour deviner o\u00f9 il avait disparu. Et soudain, j’ai r\u00e9alis\u00e9 quelque chose d’\u00e9trange : malgr\u00e9 sa t\u00e9nacit\u00e9 apparente, le l\u00e9pisme est fragile. Ses m\u00e2choires sont faibles, sa vitesse de d\u00e9placement n’est pas aussi rapide qu’elle n’y para\u00eet dans l’obscurit\u00e9. Sa seule v\u00e9ritable arme, ce sont ses \u00e9cailles argent\u00e9es. D\u00e8s qu’on le saisit, la couche protectrice se d\u00e9tache et il s’\u00e9chappe, comme une goutte de mercure qui glisse entre les doigts.<\/p>\n\n\n\n

Je me suis alors souvenu d’un autre paradoxe. Ces m\u00eames \u00e9cailles repoussent. Et les pattes repoussent. Et les antennes. Et les filaments de la queue. Alors que d’autres insectes sont condamn\u00e9s \u00e0 porter leurs blessures toute leur vie, les l\u00e9pismes muent encore et encore, jusqu’\u00e0 trente fois par an, m\u00eame \u00e0 l’\u00e2ge adulte. Cette capacit\u00e9 est presque comme une petite illusion d’immortalit\u00e9. C’est peut-\u00eatre pour cela qu’ils vivent jusqu’\u00e0 trois ans, une dur\u00e9e incroyable pour une cr\u00e9ature de leur taille.<\/p>\n\n\n\n

Mais c’est l\u00e0 que les choses se compliquent. Plus j’approfondissais la biologie de cette cr\u00e9ature, plus les faits s’\u00e9loignaient de ma peur instinctive. \u00c0 en juger par ses capacit\u00e9s, elle devrait \u00eatre la survivante par excellence. Mais en r\u00e9alit\u00e9, c’est une m\u00e9prise path\u00e9tique et radicale : sa fertilit\u00e9 est faible, moins d’une centaine d’\u0153ufs au cours de sa vie ; toute concurrence agressive, comme celle des cafards, la chasse de l’appartement en quelques mois.<\/p>\n\n\n\n

Il est presque comique de constater que nous craignons quelque chose qui a d\u00e9j\u00e0 du mal \u00e0 survivre dans le monde.<\/p>\n\n\n\n

\u00ab Alors, ils sont dangereux ?\u00bb m’a demand\u00e9 quelqu’un un jour.<\/p>\n\n\n\n

\u00ab Dangereux ?\u00bb \u00ab Plut\u00f4t timides \u00bb, ai-je r\u00e9pondu.<\/p>\n\n\n\n

Ils \u00e9vitent la lumi\u00e8re, \u00e9vitent notre nourriture, \u00e9vitent tout contact. Ils n’apparaissent que la nuit, lorsque l’humidit\u00e9 de la douche persiste pr\u00e8s du sol. Elles ne transmettent pas de maladies, ne chassent pas et ne contaminent pas les aliments. Tout au plus peuvent-elles provoquer des allergies chez les personnes hypersensibles aux minuscules particules de chitine.<\/p>\n\n\n\n

Je me suis surprise \u00e0 me poser une question qui avait presque surgi d’elle-m\u00eame : pourquoi choisissons-nous si facilement la peur l\u00e0 o\u00f9 il n’y a que la biologie ? Peut-\u00eatre parce que les mouvements nocturnes \u00e0 la limite de notre champ de vision r\u00e9veillent un instinct ancestral de m\u00e9fiance ? Ou parce que nous sommes conditionn\u00e9s \u00e0 associer tout ce qui nous est inconnu \u00e0 une menace ?<\/p>\n\n\n\n

J’ai rallum\u00e9 la lumi\u00e8re \u2013 et une fine bande argent\u00e9e a jailli avant de dispara\u00eetre, comme dissolue dans l’air chaud. Un instant fugace qui a laiss\u00e9 place \u00e0 un \u00e9trange sentiment de respect pour ce que j’avais jusque-l\u00e0 timidement \u00e9vit\u00e9.<\/p>\n\n\n\n

Et puis, tout est devenu clair : tout avait commenc\u00e9 par un mouvement soudain dans l’obscurit\u00e9 et s’\u00e9tait termin\u00e9 par la compr\u00e9hension que cette ombre sur le carrelage \u00e9tait simplement une autre forme de vie, s’accrochant au monde aussi discr\u00e8tement que nous nous accrochons \u00e0 notre paix.<\/p>\n","protected":false},"excerpt":{"rendered":"La lumi\u00e8re frappait le carrelage avec une telle force, comme si elle fendait l’air, qu’\u00e0 cet instant pr\u00e9cis, une fine ligne argent\u00e9e a \n [...]<\/a>","protected":false},"author":1,"featured_media":23159,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-23158","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-fotto"],"yoast_head":"\nUne ombre sur le carrelage : que cachent les occupants nocturnes de notre salle de bain ?
