Multiple genera of these animals are identified as “slave-making” brood parasites in a 1990 (15[1])textbook (-5[1])by Bert Hölldobler and E. O. Wilson. Doodlebugs, (15[2])which prey on these animals by hiding in (*) pits they dig in sand, are also called these animals’ “lions.” In a common (10[1])example of mutualism, some types of these animals protect aphids for access to honeydew.
