One reared specimen is at hand, a 9 , reared as an external parasite 

 of Tetragnatha laboriosa, "Agusa," Calif., May 20, 1942, E. I. Schlinger. 



This species is transcontinental in the Hudsonian, Canadian, and 

 Transition zones and occurs also in Eurasia. It occurs in dense vege- 

 tation in damp places. Adults are on the wing from early summer to 

 early fall, with a peak of abundance in July and August. Nielsen 

 reared the species from Tetragnatha obtusa in Denmark and reported on 

 its biology and pupal morphology (loc. cit.) . The type of the synonym 

 takewakii was reared from Meta reticulata. In America, the species 

 has been reared from Tetragnatha laboriosa.
