S. vicaria Walker 1853, is described from the Nearctic 

 region. It occurs across the United States and Canada 

 from Nova Scotia and Florida to British Columbia and 

 Oregon. There are no records from California, but it 

 probably occurs in the northern part of the state. 

 Climacia is found only in North and South America 

 and contains five described species. C. areolaris 

 (Hagen) 1861 and C. dictyona Needham 1901 are 

 found in the eastern United States, and C. californica 

 Chandler 1953 has been taken at Clear Lake, Lake 

 County, California, and Deschutes River, Oregon.
