Specially Protected Areas in Poodří Protected Landscape Area

Meanders of the Old Oder Nature Monument 2

Basic information

Meanders of the Old Oder Nature Monument lies on the left bank of the Oder river between Mankovice and Jeseník nad Odrou parishes in the southern part of Poodří Protected Landscape Area. This area, covering 25,96 hectares, was proclaimed a nature reserve in 1999. The territory is a representative example of the gradual succesional development of a section of the Oder river which was artificially cut off from the main flow. The bankside vegetation is of great species and age diversity. The neighboring meadows are being flooded at least once a year, forming a natural buffer zone. Periodic and permanent pools, located in this annually flooded area, are valuable wetland habitats.

The Dusky Large Blue

The Dusky Large Blue lives in extensively utilized wet meadows, sometimes even in wet ditches. The Great Burnet (Sanguisorba officinalis), a host plant for the butterlfy´s ca­terpillars, is a condition for its occurence. The second condition for the butterfly´s e­xistence is the presence of the ant Myrmica rubra. The female of the Dusky Large Blue lays eggs into the Great Burnet´s blossoms, the catepillars feed in thein ovaries for the next 2–3 weeks and then fall down on the ground, awaiting the worker ants. The ants take catepillars into their anthills and either feed them or the catepillars feed on ants´ pupae. The chrysalis stage of catepillars takes place in the anthills, where they also overwinter. In spring of the next year, a new butterfly is born.
