Study Notes
Mouthparts
- Mouthparts are structures used for feeding
- Labrum (upper lip)
- Mandible (jaw/1st jaw, lower jaw)
- Maxillae (and lower/false jaw)
- Labium (lower lip)
- Hypopharynx (tongue-like structure)
Types of Mouthparts
-
Biting and Chewing:
- Examples include grasshoppers, locusts, and cockroaches.
-
Piercing and Sucking:
- Examples include mosquitos and bugs; mouthparts are called stylets
- Housefly mandibles are absent.
-
Sponging:
-
Example includes houseflies
-
Mouthparts are modified to absorb liquids.
-
Siphoning:
- Examples include butterflies and moths.
- Maxillary palps and labia are modified for sucking flower nectar
-
Rasping and Sucking:
- Examples include thrips
-
Chewing and Lapping:
- Examples include honeybees
-
Piercing and Sucking: Example includes some beetles
-
Degenerate type:
- Examples include maggots.
- The mouthparts are not fully developed
-
Masked type:
- Examples include naiads of dragonflies
- The mouthparts are modified for catching prey
Feeding Mechanisms
- Mandibulate: Solid foods; mandibles are used to crush food.
- Haustellate: Liquid foods; mouthparts such as stylets for sucking are used to suck up liquids
- Various larval forms have specific mouthpart modifications.
Larval Forms and Insects
- Lepidotera: Caterpillars
- Coleoptera: Grub
- Diptera: Maggot
- Odonata: Naiad
- Hemiptera: Nymph
