The tissue culture laboratory of BIMET cooperate with the Environment Centre "Giorgio Nicoli" for in vitro propagation of Aristolochia rotunda as part of a larger project aimed at conservation of threatened butterfly Zerynthia polixena.

The in vitro propagation of Aristolochia will allow the propagation of a large quantity of plants to be included in the natural environment, thereby increasing the number of butterflies.

Further information:

The genus Aristolochia has about 550 species mainly distributed in all the world's tropics, subtropics and temperate regions. In Italy there are wild species, all small-flowered (A. clematidis, A. High, A. rotunda, A. pistolochia, A. longa, A. pallida), common in woods and uncultivated areas.

The plants of Aristolochia are nurses for the caterpillars of a butterfly, the Zerynthia Polyxena (Denis & Schifermuller, 1775), a beautiful butterfly with a wingspan of 50-60 mm inserted in the "Red Book of Butterflies Italian" and Annex-II IV of the Habitats Directive of the European Union as a "threatened species of butterfly in severe progressive decline from natural causes or anthropogenic factors".
