Biological notes have been recorded for only three North American species. All of them nest 

 in abandoned borings of anobiid beetles in structural timber or logs. They prey upon Thysanop- 

 tera, usually immatures although occasionally adults are captured. Some extralimital species 

 nest in twigs or decayed wood; in addition to Thysanoptera these species also prey upon imma- 

 ture Psyllidae, Coccidae and Aphididae. About a dozen undescribed species occur in the 

 southwestern deserts.
