We have found the species among thick, shaded, low-growing 

 herbaceous vegetation in low, damper parts of deciduous woods. It 

 flies low, seldom more than 30 cm. from the ground. Females com- 

 monly crawl over dead leaves of the forest floor. It is of very local 

 distribution. 



This species occurs in the Carolinian and Austroriparian faunas.
