Danube Clouded Yellow - Unnamed Site
Danube clouded yellow (Colias myrmidone)
This species is the rarest in our project: it requires a mosaic of open canopy middle forests, gently cut meadows with nectar and a food plant – broom (Chamaecytisus nigricans, Ch. ratisbonensis and Ch. supinus; in White Carpathians Ch. virescens), and places left uncut for at least one year. And all this on large areas. It has been missing in the Czech Republic since 2010 and in Slovakia, according to the latest estimates, its population is about to collapse. It is disappearing even in Romania, where until recently there were large populations.
