P. immaculata seems to be very rare in Denmark, I possess only 

 one pair, a male, taken V: 1910, probably at Damhussøen (Larsen), 

 and a female taken in Ermelund "/e 1920 (the author). The larva is a 

 snail-feeder, but I have never bred the species. 



Geographical distribution: — Europe down into Styria, towards 

 the north into Norway.
