Queen bees have mandibles with sharp cutting teeth unlike worker bees, who have toothless jaws. Male dobsonflies have slender mandibles up to 2.5 cm long, half as long as the insect's main body. Potter wasps use their mandibles to mix droplets of water with clay while constructing a nest.
The mouthparts of arthropods have evolved into a number of forms, each adapted to a different style or mode of feeding.
