L’exposition Mille milliards de fourmis s’attache à présenter leur système social et les comportements collectifs sur lesquels repose leur formidable essor ; elle explore la morphologie des fourmis et les diverses adaptations des 12 000 espèces déjà connues à ce jour.Une redécouverte de cet insecte si familier et pourtant si étonnant !

Elles arpentent le Muséum depuis le 9 mars. Les fourmis sont à l'ouvrage sous des regards passionnés.

Elles avancent par milliers et travaillent avec assurance dans les galeries de verre reconstituées à l'intérieur du Muséum, se moquant bien des travaux menés par le personnel du musée.

Avec « Mille milliards de fourmis », le musée d'Histoire naturelle de Nantes propose une toute nouvelle scénographie « in vivo », parfaite pour comprendre l'organisation et le fonctionnement d'une fourmilière.

On entre dans les coulisses comme dans un sous-bois artificiel où des fourmis exotiques transitent en toute tranquillité. « Les fourmis découpent des morceaux de feuilles souvent bien plus gros qu'elles, explique Christine Le Gourriellec du Muséum. Ensuite elles les transportent dans les tunnels de verre et rejoignent la structure du nid où se trouve le champignon, pour le nourrir avec les feuilles. En contrepartie, les larves de la fourmilière vont pouvoir se développer à l'intérieur du champignon ». Une belle symbiose à l'état naturel se déploie.

L'exposition est présentée au jusqu'au 27 février 2017 tous les jours de 10 heures à 18 heures sauf le mardi. Entrée

square Louis-Bureau. 2 ou 4 euros. Gratuit moins de 18 ans, etc.
