Conclusions 
Wax-fiber lined chambers found beneath pine and oak logs or 
stumps indicate the habitat of the nymphs and teneral adults of O. 
vicarius. We suggest that some type of symbiotic relationship exists 
between O. vicarius and the ants, Aphaenogaster carolinensis and 
Paratrechina vividula. Such a relationship is indicated by the 
repeated collections of the ants, especially Aphaenogaster, and Olia¬ 
rus in close proximity. It is also possible that the presence of Aphae¬ 
nogaster and Oliarus under the same logs is the result of similar 
habitat requirements. We suspect that the Oliarus nymphs feed on the 
exposed roots of pine, saw-palmetto, or oak that are beneath the logs.
