Round 6: Tossup 17

While observing a type of these animals known to form bivouacs (-5[1])(“BIH-voo-acks”), William Beebe observed their namesake “mill” behavior. Multiple genera of these animals (15[1])are identified as “slave-making” brood parasites (15[1])in a 1990 textbook by Bert (-5[1])Hölldobler and E. O. Wilson. Doodlebugs, (15[1])which prey on these animals by hiding in (*) pits they dig in sand, are (10[1])also called these animals’ “lions.” (10[3])In a common (10[1])example of mutualism, some types of these animals protect aphids (10[1])for access to honeydew. (10[1])Along with wasps (10[1])and bees, these insects are in the order Hymenoptera. For 10 points, what insects’ “carpenter” and (10[1])“fire” types (10[3])often form colonies? ■END■
