| Adults of some Dolichopodinae have elongate mouthparts and are known to be anthophilous and feed on nectar. |
| Dipterans typically have sucking mouthparts, and may feed on plant juices or on decaying organic matter. |
| Crustacea are characterized by two pairs of antennae, three pairs of mouthparts, and a special type of larvae called the nauplius. |
| Thrips probe plant, fungus, and animal tissues with the slender mouthparts, and suck out fluid contents. |
| Their laterally flattened bodies are covered in bristles and spines and their mouthparts are especially adapted for piercing and sucking. |
| While these mouthparts are not primarily designed to pierce skin some mallophagans do feed on blood. |
