Rearing records are from eggs of spiders, as follows: 1 from Araneus 

 diadema, several from A. angulatus, 1 from Argiope avara, 1 from 

 A. argentata, 1 from Cyriophora calif orniensis, 1 from C. calif orniensis? , 

 and 12 from "spider eggs." The usual habitat is rank shaded 

 vegetation. 



This subspecies is transcontinental in the Hudsonian, Canadian, 

 Transition, and Upper Austral zones. Adults occur throughout the 

 growing season. Egg sacs of various argiopid spiders serve as hosts.

Front wing of male 3.5 to 6.3 mm. long, of female 4.2 to 7.0 mm. 

 long; upper and lateral faces of propodeum with punctures that 

 are separated by about 1.0 to 1.2 their diameter; ovipositor sheath 

 0.43 to 0.60 as long as front wing. This subspecies averages a very 

 little stouter than T. ovivora, with the tergites a little more convex 

 and coarsely punctured, but this difference is not sufficiently great or 

 constant enough to be of real assistance in distinguishing between 

 them. 



Colored as in T. ovivora ovivora except for the following differences: 

 Face of female with a conspicuous transverse white bar below the 

 antennal sockets and laterally with a broad white stripe, these, white 

 markings covering at least 30 percent of the face, or sometimes the 

 entire face white; lower part of thorax extensively fulvous, the meta- 

 plem'um entirely fulvous; blackish markings on legs a little less 

 extensive than in T. ovivora ovivora, the apical fuscous band on hind 

 basitarsus covering its apical 0.20 ±. Sometimes in females the black 

 of the body is suffused with ferruginous, or rarely it is almost entirely 

 replaced by ferruginous. 



This subspecies can usually be distinguished from the subspecies 

 ovivora in the female with little difficulty, on account of the longer 

 ovipositor and larger amount of white on the face, though intermedi-
