S. uliginosa seems to be rare in Denmark, I only possess two 

 males, taken at Tisvilde in July (the author). 



Geographical distribution: — Europe down into Italy, but 

 upon the whole rare; it is not known north of Denmark; also recorded 

 from North-America. Kramer records it as bred from Lymantria 

 monacha and Dendrolimus pini.
