 In more complex obligate relationships (where both symbionts entirely depend on each other for survival) the ants will nest with the partner trophobionts in silk constructed leaf shelters or in underground colonies.Several species of migratory ants are noted to bring the trophobiont species with them when they move, transporting the trophobionts to new feeding areas and acting as a quick escape method if danger arises.While aphids, mealybugs and other more sedentary hemipterans are most often used as trophobionts, occasional instances of more active hemipterans such as leafhoppers have been recorded.
