The Southern festoon (Zerynthia polyxena) needs Aristolochia plants. We are planting them as part of the project.
The Southern festoon, a rare butterfly species of European importance, is bound to the warmest regions of Slovakia. The development of its monophagous caterpillars takes place on the Aristolochia plant. The restoration of these plants by direct sowing is possible, but time-consuming. However, they reproduce very well by rhizomes.
