S. siniiata is not just common in Denmark; Lersø, Dyrehaven, 

 Donse; in Jutland at Sottrup, Skeide and Hov near Odder, and on 

 Bornholm (Becker); the dates are in July. I have bred a specimen 

 from a pupa found in the ground. 



Geographical distribution: — Europe; towards the north to 

 middle Scandinavia, and in Finland. Also occurring in North America. 

 According to Aldrich (Sarcophaga and its Allies, 1916) it has been 

 bred from Melanoplus differentialis.

 mark; in Stæger's collection both are sinuata.
