Insect Mouth Parts

1.Grasshopper	labium	described as the floor of the mouth. With the maxillae, it assists manipulation of food during feeding.
	labrum	It serves to hold food in place during chewing by the mandibles
	mandibles	being used to masticate (cut, tear, crush, chew) food items.
2. Butterfly	proboscis	consists of paired galea which, during feeding, fit together to form a tube that is used to suck up nectar (it acts like a straw)
	mandibles	have a sensory function and they are used as hearing organs
	Labrum and labium	Used to chew the food and the food then goes into the mouth of the insect
3. Housefly	Proboscis	Used for sucking out the liquids
	labellum	The housefly is able to eat solid food by secreting saliva and dabbing it over the food item. As the saliva dissolves the food, the labellum acts in the usual way.
	labium	used to channel liquid food to oesophagus
4. Honeybee	mandibles(jaws)	paired "teeth" that can be open and closed to chew wood, manipulate wax, cleaning other bees, and biting other workers or pests (mites).
	proboscis	proboscis is mainly used for sucking in liquids such as nectar, water and honey inside the hive, for exchanging food with other bees (trophallaxis), and also for removing water from nectar
	mandibular gland	which secretes a substance once thought to be used to soften wax
