Top half of the "notch" is visible just above the hindwing in the red/orange
 post discal area of the underside forewing. This feature separates styx
from the very closely similar Stygian Ringlet, E. stirius.

 

N Italy, June 2004

 


This seems to be a very local species although it is supposedly widespread from eastern Switzerland and neighbouring N. Italy across the Alps of southern Austria and Slovenia. I've only seen it at 2 sites. My best site is very low at 300m where I found it in mid June in 2003 and reasonably fresh at the end of June 2004. I understand that this is exceptionally low and early, being more usually found at Alpine levels but as low as 600m and usually not before the beginning of July.

It flies extremely locally at both places I've found it, straying not one bit from the breeding ground. It may actually be more accurate to say that it strays not far from patches of its habitat that are flat enough for humans to cross as they live on very steep cliff faces with patches of grass where presumably eggs are laid and left in peace.
