a broad spectrum of social behaviors have been observed in the tropical "augochloropsis" species. these range from solitary, to communal, semisocial, and even eusocial nesting behavior. a few faunal studies have looked at north american species as well. "a. sumptuosa" has been studied in new jersey and kansas and has been found to be either communal or semisocial. some species have been observed to nest in aggregations, where the openings of several nests are located within just centimeters of each other.
