Superfamily Argiopoidea 



I have found similar webs very common on the rough bark 

 of the trunks of elm trees on the Cornell Campus. In 

 these cases, the retreat of the spider was beneath a scale of 

 the bark. 



There is in our collection a web, which I believe to be of this 

 species, and which was made on a dead branch on a larch tree 



Fig. 266. WEB OF DICTYNA SUBLATA 



(Fig. 266). In this web the characteristic form of the entrance 

 to the retreat is well-shown. 



The adult spiders can be found in their webs in early summer. 

 It is evident that they reach maturity in the autumn or early 

 The egg-sacs are made early in June; and then follows

spring.
